Small 116 patient RCT with low-risk patients comparing ivermectin+doxycycline and HCQ+AZ, showing lower hospitalization, higher viral clearance, and faster symptom resolution and viral clearance with ivermectin+doxycycline. Mid-recovery resolution of symptoms is statistically significantly better with treatment, while other measures do not reach statistical significance. Instructions were to take ivermectin on an empty stomach, reducing lung tissue concentration. NCT04434144
Chowdhury et al., 7/14/2020, Randomized Controlled Trial, Bangladesh, South Asia, peer-reviewed, 6 authors, dosage 200μg/kg single dose, this trial compares with another treatment - results may be better when compared to placebo, this trial uses multiple treatments in the treatment arm (combined with doxycycline) - results of individual treatments may vary.
risk of hospitalization, 80.6% lower, RR 0.19, p = 0.23, treatment 0 of 60 (0.0%), control 2 of 56 (3.6%), continuity correction due to zero event (with reciprocal of the contrasting arm).
risk of no recovery, 46.4% lower, RR 0.54, p < 0.001, treatment 27 of 60 (45.0%), control 47 of 56 (83.9%), mid-recovery day 5.
recovery time, 15.2% lower, relative time 0.85, p = 0.07, treatment 60, control 56.
risk of no virological cure, 80.6% lower, RR 0.19, p = 0.23, treatment 0 of 60 (0.0%), control 2 of 56 (3.6%), continuity correction due to zero event (with reciprocal of the contrasting arm).
time to viral-, 4.3% lower, relative time 0.96, p = 0.23, treatment 60, control 56.
Effect extraction follows pre-specified rules
prioritizing more serious outcomes. For an individual study the most serious
outcome may have a smaller number of events and lower statistical signficance,
however this provides the strongest evidence for the most serious outcomes
when combining the results of many trials.
