Retrospective 237 patients in Turkey (March 2020 - January 2021) Study compares with HCQ, results vs. placebo may differ Lower hospitalization (p=0.0012) and faster viral clearance (p=0.001) c19early.org Turan et al., The Brazilian J.

Retrospective 237 low-risk healthcare workers in Turkey, 123 treated with favipiravir and 114 treated with HCQ, showing lower hospitalization and faster viral clearance with favipiravir, and similar improvement. This study is subject to substantial confounding by time because the patients in each group are from different time periods with an overall period of 10 months including the beginning of the pandemic, resulting in significant differences in variants encountered and SOC. Propensity for hospital admission may also have changed significantly.
Potential risks include the creation of dangerous variants, and mutagenicity, carcinogenicity, teratogenicity, and embryotoxicity1-5.
This study is excluded in meta analysis: substantial confounding by time likely due to separation of groups in different time periods over an extended period of time.
risk of hospitalization, 79.4% lower, RR 0.21, p = 0.001, treatment 4 of 123 (3.3%), control 18 of 114 (15.8%), NNT 8.0.
recovery time, 11.0% higher, relative time 1.11, p = 0.51, treatment 123, control 114.
time to viral-, 21.6% lower, relative time 0.78, p < 0.001, treatment 123, control 114.

Objectives: Comparative data on hydroxychloroquine and favipiravir, commonly used agents in the treatment of Coronavirus Disease-2019 (COVID-19), are still limited. In this study, it was aimed to compare treatment outcomes in healthcare workers with COVID-19 who were prospectively followed by the occupational health and safety unit. Methods: A total of 237 healthcare-workers, diagnosed as mild or moderate COVID-19 between March 11, 2020 and January 1, 2021, were given hydroxychloroquine (n = 114) or favipiravir (n = 123). Clinical and laboratory findings were evaluated. Results: The mean age of the patients was 33.4 §11.5 years. The mean time to negative PCR was found to be significantly shorter in patients receiving favipiravir compared to the hydroxychloroquine group (10.9 vs. 13.9 days; p < 0.001). The rate of hospitalization in the hydroxychloroquine group was significantly higher than favipiravir group (15.8% vs. 3.3%). In terms of side effects; the frequency of diarrhea in patients receiving hydroxychloroquine was significantly higher than that in the favipiravir group (31.6% vs. 6.5%; p < 0.001). Conclusions: Favipiravir and hydroxychloroquine were similar in terms of improvement of clinical symptoms of healthcare workers with mild or moderate COVID-19 infection, but favipiravir was significantly more effective in reducing viral load and hospitalization rates. Furthermore, favipiravir caused significantly less side-effects than hydroxychloroquine.
