FIGURE 4.
Receiver operating characteristic (ROC) curve analysis to assess the predictive value of baseline parameters. (A) ROC curve for predicting the HGS improvement (5% or more) based on the baseline HGS, ASM, and height. (B) ROC curve for predicting the 5TSTS improvement (5% or more) based on baseline Hb and Hct levels. ROC curves in this figure are as drawn smaller test result indicates more positive test. (C) The area under curve (AUC), cut-off values, sensitivity and specificity, and positive and negative predictive values of the test are presented in the table. HGS, handgrip strength; 5TSTS, five-times sit-to-stand test; ASM, appendicular skeletal muscle mass; Hb, hemoglobin; Hct, hematocrit.
