RCT for ivermectin+doxycycline showing improvements in mortality, recovery, progression, and virological cure. 183 treatment and 183 control patients with no deaths in the treatment arm vs. 3 in the control arm (the 3 control deaths are not included in the analysis of other outcomes). Results may reflect the use of ivermectin, doxycycline, and potential synergistic effects of the combination. In the PRINCIPLE trial, no mortality benefit was seen for doxycycline alone1 (0.6% mortality with doxycycline vs. 0.2% control).
This is the 6th of 51 COVID-19 RCTs for ivermectin, which collectively show efficacy with p=0.00000015.
This is the 11th of 104 COVID-19 controlled studies for ivermectin, which collectively show efficacy with p<0.0000000001 (1 in 1 sextillion).
risk of death, 85.7% lower, HR 0.14, p = 0.25, treatment 0 of 183 (0.0%), control 3 of 183 (1.6%), NNT 61, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).

Journal of International Medical Research, doi:10.1177/03000605211013550
Objective: We evaluated whether ivermectin combined with doxycycline reduced the clinical recovery time in adults with COVID-19 infection. Methods: This was a randomized, blinded, placebo-controlled trial in patients with mild-tomoderate COVID-19 symptoms randomly assigned to treatment (n ¼ 200) and placebo (n ¼ 200) groups. The primary outcome was duration from treatment to clinical recovery. Secondary outcomes were disease progression and persistent COVID-19 positivity by RT-PCR.
Declaration of conflicting interest The authors declare that there is no conflict of interest. Popular Pharmaceuticals Limited, Bangladesh provided ivermectin, doxycycline, and placebo. The company was not involved in the planning or design of the study and had no role in the collection, analysis, or interpretation of the data. Author contributions Appendix
