In the 0–90 day window, however, additional adjustment for age slightly strengthened the association and improved statistical significance (OR=1.056, 95% CI 1.008 to 1.108, p=0.023), compared with the marginally non-significant estimate without age adjustment (OR=1.046, 95% CI 0.999 to 1.095, p=0.056) ( online supplemental table S5 ).
