Association of ABO Blood Types and Clinicopathological Features of Prostate Cancer

Table 4

Multivariate analysis to identify the independent correlation between non-O blood type and high risk of PC.

Models	Variables	Multivariate model		value
		OR	95% CI
1	Non-O	2.280	1.152–4.512	0.018
2	Model 1 + covariates	2.443	1.215–4.914	0.012
3	Model 2 + PSA	3.525	1.221–10.178	0.020
4	Model 3 + Gleason score	33.066	2.391–457.323	0.009

Multivariate regression stepwise models are shown. The bold value indicated statistical significance. The dependent variable was high-risk PC. Model 1 was unadjusted. Model 2 corrected for covariates including age, body mass index, hypertension, diabetes mellitus, and coronary artery disease. Model 3 additionally corrected for PSA based on Model 2; Model 4 additionally corrected for Gleason Score based on Model 3. PSA = prostate-specific antigen; PC = prostate cancer.
