Figure 3: SAD and adverse surgical outcomes in the transperitoneal subgroup
u-SAD : Umbilical sagittal abdominal diameter, WHR : Waist-hip ratio, BMI : Body mass index, AUC : area under the curve (accuracy)
(a) Mean umbilical SAD measurements in patients with and without surgical morbidity were 249 mm (95%CI, 233–265) and 219 mm (95%CI, 207–231), respectively.
(b) Surgical morbidity rate according to u-SAD measurements in the transperitoneal and extraperitoneal subgroups.
(c) Comparison of diagnostic accuracy of three anthropometric measurements to assess surgical morbidity. AUC values (95%CI) for u-SAD, WHR and BMI were as follows: 0.73 (0.59–0.86), 0.71 (0.57–0.85), and 0.67 (0.52–0.83). Comparison of u-SAD vs. WHR and u-SAD vs. BMI were not significant (p =0.4 and p =0.17, respectively).
(d) Diagnostic accuracy of u-SAD in the transperitoneal vs. extraperitoneal subgroups. AUC 0.73 (95%CI, 0.59–0.86) vs 0.50 (95%CI, 0.35–0.65), respectively.
