Spearman rho is listed for continuous variables. For binary variables, TAC scores for each group are displayed as median (Interquartile range). Unadjusted P value from Wilcoxon rank sum test or Spearman’s correlation test. Adjusted P value from a multivariable proportional odds regression model with tibial artery calcification scores as outcome and age, BMI, race, gender, smoking history, hypertension, race, hyperlipidemia, and peripheral occlusion index as covariates.
