2 Fig. 1 ROC curves: Predictive performance of ultrasound for the pathologic diagnosis of appendicitis stratified by pregnancy status. Pregnant group: AUC = 0.76 (95%CI 0.64–0.87); Nonpregnant group: AUC = 0.73 (95%CI: 0.63–0.83) p = 0.78.

3 Fig. 2 ROC curves: Predictive performance of ultrasound for the pathologic diagnosis of appendicitis in pregnant patients, stratified by trimester. Trimester 1 (n = 23): AUC = 0.73 (95%CI: 0.4–1.0); Trimester 2 (n = 32): AUC = 0.67 (95%CI: 0.49–0.87); Trimester 3 (n = 12): AUC = 0.86 (95%CI: 0.68–1.0) p = 0.4.
