Nitazoxanide in Patients Hospitalized With COVID-19 Pneumonia: A Multicentre, Randomized, Double-Blind, Placebo-Controlled Trial
RCT late stage patients with COVID-19 pneumonia, 202 treated with nitazoxanide and 203 placebo patients, showing improved recovery, but no significant difference in mortality.
risk of death, 4.9% higher, RR 1.05, p = 0.94, treatment 6 of 202 (3.0%), control 5 of 203 (2.5%), adjusted per study, odds ratio converted to relative risk, multivariable, day 14.

risk of ICU admission, 30.5% lower, RR 0.69, p = 0.18, treatment 20 of 202 (9.9%), control 30 of 203 (14.8%), NNT 21, adjusted per study, odds ratio converted to relative risk, multivariable, day 14.

risk of oxygen therapy, 39.7% lower, RR 0.60, p = 0.06, treatment 22 of 202 (10.9%), control 33 of 203 (16.3%), NNT 19, adjusted per study, odds ratio converted to relative risk, multivariable, day 14.

time to improvement, 63.6% lower, HR 0.36, p < 0.001, treatment 202, control 203, inverted to make HR<1 favor treatment, Kaplan–Meier.

improvement, 34.2% better, OR 0.66, p = 0.14, treatment 202, control 203, adjusted per study, inverted to make OR<1 favor treatment, multivariable, day 14, RR approximated with OR.

time to discharge, 27.0% lower, HR 0.73, p = 0.004, treatment 202, control 203, inverted to make HR<1 favor treatment, Kaplan–Meier.

discharge, 8.3% lower, OR 0.92, p = 0.82, treatment 202, control 203, adjusted per study, inverted to make OR<1 favor treatment, multivariable, day 14, RR approximated with OR.
