Comparing the diagnostic accuracy of modified RIPASA and MASS in patients diagnosed with acute appendicitis in Suez Canal University Hospital Emergency Department: a cross-sectional study

Table 6 Area under the curve for modified RIPASA as a predictor of acute appendicitis

Variable	AUC	Stand. error	p-value	95% CI	Cut-off point	Sensitivity	Specificity
RIPASA	0.902	0.053	0.002*	(0.798 – 1.00)	8.5	70.6%	100%

Our study shows receiver operating characteristic curves for modified RIPASA as a predictor of acute appendicitis. Modified RIPASA showed a good discriminative ability where the area under the curve for modified RIPASA was 0.902 (95% CI: 0.798 – 1.00) (p = 0.002). Moreover, a value of 8.5 or higher was found to be the best cut-off point to predict acute appendicitis among patient with suspected clinically acute appendicitis with sensitivity = 70.6% and specificity = 100%
