In univariate analysis, PoAF was found to significantly correlate with age (odds ratio [OR]: 1.151, 95% confidence interval [CI]: 1.008-1.244, P<0.001), HT (OR: 0.824, CI: 0.756-0.978, P=0.026), COPD (OR: 0.653, CI: 0.312-0.776, P=0.023), lymphocyte counts (OR: 0.396, CI: 0.294-0.804, P=0.010), C-reactive protein (OR: 1.050, CI: 1.008-1.212, P=0.028), PNI (OR: 1.024, CI: 1.010-1.196, P=0.002), and VAI (OR: 1.412, CI: 1.186-1.697, P<0.001), and not correlate with TG levels. This evidence concerns the gene CRP and chronic obstructive pulmonary disease.
