(A) Nomogram, (B) calibration plot, and (C–E) conditional probability plots for prediction of the individual probability of urinary continence recovery after radical prostatectomy (RP). Nomogram instructions: Locate the patient's value for each individual predictor, and draw a line straight up to the point axis to determine how many points toward the probability of urinary continence recovery the patient receives for each predictor. Sum the points for each of the predictors. Locate the value corresponding to the sum on the total point axis (A). Subsequently, choose the time point of interest after RP (6, 12, or 24 mo) (C–E). Within the specific time point panel, draw a line straight up from the total point's axis. Then draw a horizontal line from a value on the y-axis that corresponds to the number of months without recovery of urinary continence that elapsed between RP and the current time. Use the intersection of both lines to identify a slanted line that crosses it or passes next to it. Follow the slanted line down to the x-axis to determine the probability of urinary continence recovery at the prespecified number of months.
