Table 3 Comparison of area under curve (AUC) after a receiver operating characteristic analysis between prediction models

From: Combination of measures of handgrip strength and red cell distribution width can predict in-hospital complications better than the ASA grade after hip fracture surgery in the elderly

  AUC 95% confidence interval
ASA grade 0.61 0.50 to 0.72
Grip strength 0.73 0.63 to 0.83
RDW + Grip strength 0.75 0.64 to 0.84
ASA grade + other variables* 0.75 0.64 to 0.84
RDW + Grip strength + other variables* 0.78 0.67 to 0.86
