Abbreviation: PY = person-years, cSHR = crude subdistribution hazard ratio, CI = confidence interval, aSHR = adjusted subdistribution hazard ratio, BH = Benjamini–Hochberg procedure

^aIncidence rate, per 100,000 person-years.

^bAdjusted for sex, age, area of residence, urbanization, income, and CCI.

^c 95% CIs were not adjusted for multiple comparisons and thus cannot be directly used for hypothesis testing or inference.
