Each panel plots the same axes. The horizontal axis is labeled “1 minus Specificity” and ranges from 0.00 to 1.00 in increments of 0.25 units. The vertical axis is labeled “Sensitivity” and ranges from 0.00 to 1.00 in increments of 0.25 units. Each panel includes a diagonal reference line from (0.00, 0.00) to (1.00, 1.00). In all three panels, the R O C curve rises concave down from 0.00 on the horizontal axis and then gradually approaches sensitivity 1.00 as 1 minus specificity increases, remaining above the diagonal reference line. The reported area under the R O C curve values are 0.7660 in the left panel, 0.7599 in the middle panel, and 0.7588 in the right panel.ROC curve for logistic regression models. Source: Own elaboration
