Analyses include participants with 0 values for NCV. When analyses were repeated excluding participants with 0 values for NCV differences in peroneal NCV between participants with IC and those who were always asymptomatic were no longer statistically significant.
Analyses adjust for age, sex, race, BMI, ABI, comorbidities, recruitment cohort, cigarette smoking, height, lower extremity revascularization, and alcohol use.
P= 0.0002
P= 0.0051
P= 0.0056 for pairwise comparisons of always asymptomatic PAD participants vs IC.
