Comparative performance of the 3 scores/model for the prediction of patients with inadequate bowel preparation in the entire cohort. (A) Comparison of independent receiver operating characteristics curves for the 3 scores/model. (B) Kiviat diagram consisting of a sequence of equiangular spokes, called radii, with each spoke representing one of the variables. The data length of a spoke is proportional to the magnitude of the variable in the model. (C) Calibration curve for the 3 scores/models
