Data of 110 women with LPP and 72 without LPP were available. The advantages and disadvantages of four cutoff points of ASLR, and combinations of the ASLR and PPPP, were investigated by comparing sensitivity, specificity and area under the curves (AUC) of receiver operating characteristic curves (ROC). The influence of the site of pain was analyzed by means of AUC. The relation with confounders was measured using Pearson correlation coefficients.
