  • *Means and percentages were adjusted for survey weights of NHANES.

  • †Smoking was defined as smoking at least 100 cigarettes during their lifetime.

  • ‡Alcohol use was defined as having at least 12 alcohol drinks in any given year.

  • §BMI was calculated by dividing weight in kilograms (kg) by height in metres squared (m2). Participants were classified as normal weight (<25 kg/m2), overweight (25–29.9 kg/m2) and obese (≥30 kg/m2).

  • BMI, body mass index; CRP, C reactive protein; dNLR, derived NLR; GED, general equivalency diploma; LUTS, lower urinary tract symptoms; Lym, lymphocyte; MLR, monocyte to lymphocyte ratio; Mono, monocyte; Neu, neutrophil; NHANES, National Health and Nutrition Examination Survey; NLR, neutrophil to lymphocyte ratio; PIV, pan-immune-inflammation value; PLR, platelet to lymphocyte ratio; PLT, platelet; SII, systemic immune-inflammation index; SIRI, System Inflammation Response Index; WCC, white cell count.
