Comparison of antiviral effect for mild-to-moderate COVID-19 cases between lopinavir/ritonavir versus hydroxych loroquine: A nationwide propensity score-matched cohort study
Health insurance database analysis failing to adjust for disease severity and not finding a significant difference in time to PCR- for LPV/r and HC
There are large differences in severity across groups. Authors did PSM but chose not to prioritize severity, resulting in incomparable groups, e.g., baseline pneumonia of 44% in the HC
Q group and 15% in the control group (after PSM).
Authors note this but offer no explanation for not correcting for severity: "However, the disease severity and proportion of accompanying pneumonia were still significantly higher in the LPV/r and HC
