  • ↵a Percentages refer to the number of patients with non-missing values. P values are from the likelihood ratio test using propensity scores and odds ratios, and resulting 95% confidence intervals are derived from the logistic model that includes both treatment and propensity scores (see “Materials and Methods” section).
