Table 3 Logistic regression for plasma Hsp27

From: Plasma heat shock protein 27 is associated with coronary artery disease, abdominal aortic aneurysm and peripheral artery disease

Group/binary threshold	Univariate odds ratio			Adjusted* odds ratio
	Odds ratio	95% CI	P value	Odds ratio	95% CI	P value
All CAD (n = 80), Hsp27 > 2.24	0.17	0.08-0.34	0.0001	0.21	0.10-0.42	0.0001
PAD (n = 40), Hsp27 > 2.69	0.36	0.16-0.81	0.013	0.25	0.09-0.71	0.009
AAA (n = 80), Hsp27 > 2.75	0.43	0.22-0.82	0.011	0.29	0.12-0.69	0.005
All disease patients (n = 200), Hsp27 > 2.63	0.32	0.18-0.55	0.001	0.21	0.10-0.42	0.001
PAD & AAA (n = 120), Hsp27 > 2.63	0.40	0.22-0.72	0.002	0.26†	0.17-0.56	0.006

Logistic regression analysis was used to calculate the odds ratios for having plasma Hsp27 levels above binary thresholds. The reference population was the elderly control group. The adjusted model 1* included age, gender, history of hypertension, dyslipidemia, diabetes, smoking (pack years) and high sensitivity C-reactive protein. Adjusted model 2† included all factors in model 1 plus history of CAD.
