OR odds ratio, CI confidence interval.
aTrend test was calculated for the associations between alcohol use patterns as a continuous variable and incident cataract surgery.
bConditional logistic regression matched for sex, age, admission date, and hospital.
cAdditionally adjusted for smoking history, lifestyle-related comorbidities (hypertension, hyperlipidaemia, diabetes, and obesity), occupational radiation exposure, and outdoor work.
