Table 3 Development of a bleeding risk model in elderly patients with AF undergoing PCI

Variables	Category	Odds ratio	95% CI	Scores
eGFR ^a (mL/min/1.73m²)	< 30	1.534	0.798–2.951	+ 2
	30–45			+ 1
	> 45			+ 0
Age (years)	≤ 80 vs. > 80	2.023	0.834–4.905	+ 1
Multivessel disease	(–) vs. (+)	2.738	1.175–6.381	+ 1
History of surgery	(–) vs. (+)	3.661	1.311–10.221	+ 2
Hypertension	(–) vs. (+)	2.502	0.828–7.565	+ 1
Anemia ^b	(–) vs. (+)	2.132	0.819–5.551	+ 1

Odds ratios = Exp(β); CI, confidence interval; eGFR, estimated glomerular filtration rate
a: eGFR was stratified into 3 groups (< 30, 30–45, > 45) (unit: mL/min/1.73m²)
b: Anemia was defined as a history of anemia or hemoglobin level < 11 (unit: g/dL)
