CRP and benign prostatic hyperplasia: After adjusting for confounders (such as age, disease duration, prostate volume, total prostate-specific antigen, C-reactive protein, post-voided residual urine, urea nitrogen, etc.), current smoking (OR = 1.995, 95%CI:1.270–3.134), unhealthy dietary habits (OR = 1.590, 95%CI: 1.059–2.386), and lack of active exercise (OR = 1.996, 95%CI:1.274–3.127) were positively correlated with the severity of BPH/LUTS.
