Comparison of linemen with non-linemen. The Wilcoxon rank sum test was used for continuous variable; Fisher exact test for binary variables. Only 128 observations were available for body fat.
BMI refers to body mass index; BP, blood pressure; NSAID, nonsteroidal antiinflammatory drugs; LDL, low-density lipoprotein; HDL, high-density lipoprotein.
