Clinical Variants, Characteristics, and Outcomes Among COVID-19 Patients: A Case Series Analysis at a Tertiary Care Hospital in Karachi, Pakistan
Retrospective 165 hospitalized patients in Pakistan showing unadjusted lower mortality with combined ivermectin and doxycycline treatment. Details of the ivermectin group compared to other patients are not provided, however ivermectin was given to a similar percentage of patients in the mild, moderate, and severe/critical groups (34.5%, 29.1%, and 36.4%), suggesting that ivermectin treatment was not based on severity.
Ahsan et al., 4/29/2021, retrospective, Pakistan, South Asia, peer-reviewed, 10 authors, dosage 150μg/kg days 1-2, 150-200µg/kg, this trial uses multiple treatments in the treatment arm (combined with doxycycline) - results of individual treatments may vary.
risk of death, 50.0% lower, RR 0.50, p = 0.03, treatment 17 of 110 (15.5%), control 17 of 55 (30.9%).
This study is excluded in meta analysis: unadjusted results with no group details.
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.
