All observations were weighted by stabilized inverse propensity of treatment weights. Values are reported as mean ± standard deviation for continuous variables and percentages for categorical variables. P-values are from chi-square tests for categorical variables and t-tests for continuous variables, using the Satterthwaite approximation when variances were unequal across cohorts at a significance level of 0.05
