P values were calculated using the Pearson χ² test, Fisher’s exact test, or the Fisher-Freeman-Halton exact test, as appropriate. All tests were two-sided. Risk differences and corresponding 95% confidence intervals for the primary outcome and selected clinically relevant secondary outcomes were calculated from raw 2 × 2 contingency tables using the Newcombe score method, without multivariable adjustment. Risk differences were calculated as the proportion in the ≥ 65-year group minus that in the < 65-year group. RD: Risk difference; CI: Confidence interval.
