Fig. 3From: A nomogram for predicting bowel obstruction in preoperative colorectal cancer patients with clinical characteristicsNomogram developed for predicted BO among patients with CRC. Locate the patient’s age and draw a straight line toward the “points” axis to determine the score associated with that age. Repeat the process for each variable, sum the scores obtained for each covariate, and locate this sum on the “total points” axis. Draw a straight line straight downwards to determine the likelihood of 90- or 180-day BO rateBack to article page
