HCQ is effective for COVID-19 when used early (118 studies)

Article is HCQ is effective for COVID-19 when used early: analysis of 118 studies.  Excerpts in italics with my bolds.

HCQ is an effective treatment for COVID-19. The probability that an ineffective treatment generated results as positive as the 118 studies to date is estimated to be 1 in 23 million (p = 0.000000043).

Early treatment is most successful, with 100% of studies reporting a positive effect and an estimated reduction of 63% in the effect measured (death, hospitalization, etc.) using a random effects meta-analysis, RR 0.37 [0.30-0.47].
100% of Randomized Controlled Trials (RCTs) for early, PrEP, or PEP treatment report positive effects, the probability of this happening for an ineffective treatment is 0.002.
•There is evidence of bias towards publishing negative results. Significantly more retrospective studies report negative results compared to prospective studies, p = 0.04.
•Significantly more studies in North America report negative results compared to the rest of the world, p = 0.002.

Figure 2: Treatment stages.

Figure 2 shows stages of possible treatment for COVID-19. Pre-Exposure Prophylaxis (PrEP) refers to regularly taking medication before being infected, in order to prevent or minimize infection. In Post-Exposure Prophylaxis (PEP), medication is taken after exposure but before symptoms appear. Early Treatment refers to treatment immediately or soon after symptoms appear, while Late Treatment refers to more delayed treatment.

Publication bias. Publishing is often biased towards positive results, which we would need to adjust for when analyzing the percentage of positive results. Studies that require less effort are considered to be more susceptible to publication bias. Prospective trials that involve significant effort are likely to be published regardless of the result, while retrospective studies are more likely to exhibit bias. For example, researchers may perform preliminary analysis with minimal effort and the results may influence their decision to continue. Retrospective studies also provide more opportunities for the specifics of data extraction and adjustments to influence results.

For HCQ, 87.5% of prospective studies report positive effects, compared to 69.8% of retrospective studies, two-tailed z test 2.07, p = 0.04, indicating a bias toward publishing negative results.

The lack of bias towards positive results is not very surprising. Both negative and positive results are very important given the current use of HCQ for COVID-19 around the world, evidence of which can be found in the studies analyzed here, government protocols, and news reports, for example [AFP, AfricaFeeds, Africanews, Afrik.com, Al Arabia, Al-bab, Anadolu Agency, Anadolu Agency (B), Archyde, Barron’s, Barron’s (B), BBC, Belayneh, A., CBS News, Challenge, Dr. Goldin, Efecto Cocuyo, Expats.cz, Face 2 Face Africa, France 24, France 24 (B), Franceinfo, Global Times, Government of China, Government of India, GulfInsider, Le Nouvel Afrik, LifeSiteNews, Medical World Nigeria, Medical Xpress, Medical Xpress (B), Middle East Eye, Ministerstva Zdravotnictví, Morocco World News, Mosaique Guinee, Nigeria News World, NPR News, Oneindia, Pan African Medical Journal, Parola, Pilot News, Pleno.News, Q Costa Rica, Rathi, Russian Government, Teller Report, The Africa Report, The Australian, The BL, The East African, The Guardian, The Indian Express, The Moscow Times, The North Africa Post, The Tico Times, Ukraine Ministry of Health Care, Ukrinform, Vanguard, Voice of America].

We also note a bias towards publishing negative results by certain journals and press organizations, with scientists reporting difficulty publishing positive results [Boulware, Meneguesso]. Although 88 studies show positive results, The New York Times, for example, has only written articles for studies that claim HCQ is not effective [The New York Times, The New York Times (B), The New York Times (C)]. As of September 10, 2020, The New York Times still claims that there is clear evidence that HCQ is not effective for COVID-19 [The New York Times (D)]. As of October 9, 2020, the United States National Institutes of Health still recommends against HCQ for both hospitalized and non-hospitalized patients [United States National Institutes of Health].

Treatment details. We focus here on the question of whether HCQ is effective or not for COVID-19. Significant differences exist based on treatment stage, with early treatment showing the greatest effectiveness. 100% of early treatment studies report a positive effect, with an estimated reduction of 63% in the effect measured (death, hospitalization, etc.) in the random effects meta-analysis, RR 0.37 [0.30-0.47]. Many factors are likely to influence the degree of effectiveness, including the dosing regimen, concomitant medications such as zinc or azithromycin, precise treatment delay, the initial viral load of patients, and current patient conditions.

News website Panorama.it has launched a petition to get the drug hydroxychloroquine officially reinstated so that Italian doctors can once again use it with patients. If not, some of them will go ahead and use it anyway. The retracted Lancet study and trials using lethal doses(!) of HCQ were enough to get it officially banned in Italy as in other countries. Except the Italian Medicines Agency (AIFA) has not yet reapproved it, despite studies showing its effectiveness. Here are excerpts of the Change.org petition translated from Italian:

At the moment there are no treatments of proven effectiveness to be administered at home. Because the only therapy that AIFA (Italy’s Medicines Agency) had authorized at home, the one based on hydroxychloroquine, has been blocked. It happened on May 26, after the publication of a study in The Lancet, which was withdrawn 13 days later.

Meanwhile, German GPs, who had administered 1,060,000 doses of hydroxychloroquine in March, continued to prescribe it. In the United States, three states lifted the ban on the drug in early August. In China, on August 19, the National Health Commission’s guidelines continued to recommend the active ingredient for Covid 19 patients. And on September 21, The Lancet itself retraced its steps, with a study claiming that hydroxychloroquine reduces mortality.

In order to save lives, we ask AIFA to restore the use of hydroxychloroquine for home patients in the very early stages of the disease, possibly even with an emergency procedure. Otherwise, we invite the Agency to provide shared protocols of treatment practicable in the territory.

    Missouri has begun the most effective prophylaxis by holding the communist party dictatorship over China liable for damages. Forty nine other States and ten Provinces could deter additional bio-weapon attacks by following suit. Superstitious American politicians did something similar to Peru by attacking crops with Fusarium. Their political parties too should be held liable for the damages, with the hierarchy feeling asset forfeiture on its own hide, bank accounts, securities holdings, and real estate. Replacing the Communist, Republican and Democratic parties with political organizations bent on replacing aggressive coercion with free and voluntary solutions may not be easy. Dipping sheep, worming dogs and removing the ticks from cattle also involve effort, but the results invariably prove well worth the effort.

    ATTENTION: People need get prescriptions of Hydroxychloroquine and Azithromycin in advance of a COVID-19 infection and be prepared if/when it strikes.

    These 2 cheap prescription drugs along with over the counter products such as Zinc, Vitamin C, Vitamin D3, Aspirin, Pepcid, Melatonin, and Quercetin is being prescribed by many doctors and is also available via the phone app MEDICI. MEDICI is staffed by on-line doctors who highly recommend this Hydroxychloroquine based treatment at the onset of COVID symptoms… and not to wait until after the person is infected to get these proven meds.

    If your doctor doesn’t agree with using Hydroxychloroquine, then find another doctor or use the MEDICI app to speak with a doctor immediately… no waiting, no appointments. These prescriptions only cost a few dollars without insurance. Hydroxychloroquine has been used for decades to treat malaria and has minimal side effects. Azithromycin is a well tested general antibiotic used to fight any secondary bacterial infection that may develop.

    In most cases the COVID-19 symptoms and time of recovery are significantly reduced by taking Hydroxychloroquine early on when infected. Additionally, the mortality rate from the COVID-19 disease is significantly reduced with the use of Hydroxychloroquine. Be prepared and get these prescriptions now.
