Small prospective PSM study in the USA, showing 75% lower mortality with ivermectin treatment, without reaching statistical significance, significantly shorter ventilation and ICU time, and longer hospitalization time.
Authors leave the statistically significant improvements in ventilation and ICU time out of the abtract and conclusions, and incorrectly state that there were no differences in other outcomes (there were no statistically significant differences): . Authors are ambiguous on the primary outcome, referring to the primary mortality outcome in one case, and "clinical outcomes, measured by the rate of intubation, length of hospital stay, and mechanical ventilation duration" in another case.
risk of death, 75.0% lower, RR 0.25, p = 0.09, treatment 2 of 60 (3.3%), control 8 of 60 (13.3%), PSM.
risk of mechanical ventilation, 12.6% lower, RR 0.87, p = 0.20, treatment 3 of 60 (5.0%), control 2 of 60 (3.3%), odds ratio converted to relative risk, PSM, multivariable.
ventilation time, 83.3% lower, relative time 0.17, p = 0.002, treatment 60, control 60.
risk of ICU admission, 48.7% lower, RR 0.51, p = 0.42, treatment 6 of 60 (10.0%), control 3 of 60 (5.0%), odds ratio converted to relative risk, PSM, multivariable.
ICU time, 70.6% lower, relative time 0.29, p < 0.001, treatment 60, control 60.
hospitalization time, 9.0% higher, relative time 1.09, p = 0.09, treatment 60, control 60, PSM, multivariable.

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.
