Incidence of MACCE according to drinking habit change after PCI.

Alcohol Status Pre PCI/Post PCI	n	Events (n)	Follow-Up Duration (Person-Years)	Incidence Rate (per 1000 Person-Years)	IPW * Adjusted HR (95% CI)
Non/Non	26,453	4761	85,227	55.863	1 (ref)
Non/Drinking	2467	384	8569	44.815	0.849 (0.775 to 0.930)
Drinking/Non	8291	1487	27,276	54.518	0.952 (0.900 to 1.008)
Drinking/Drinking	13,581	1906	44,363	42.964	0.777 (0.735 to 0.821)

CI = confidence interval; HR = hazard ratio; MACCE = Major adverse cardiovascular and cerebrovascular events; PCI = percutaneous coronary intervention. * IPW model: Weights are calculated by age, sex, hypertension, diabetes mellitus, dyslipidemia, body mass index, social income, regular exercise, and smoking status.
