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 9 Area under the curve for MASS as a predictor of acute appendicitis

Variable	Area	Stand. error	p-value	95% CI	Cut-off point	Sensitivity	Specificity
MASS	0.324	0.095	0.173	(0.137 – 0.510)	5.5	47.1%	33.3%

Our study shows receiver operating characteristic curves for MASS as a predictor of acute appendicitis Table 5 The area under the curve for MASS was 0.324 (95% CI: 0.137 – 0.510) (p = 0.173). Moreover, a value of 5.5 or higher was found to be the best cut-off point to predict acute appendicitis among patient with suspected clinically acute appendicitis with sensitivity = 47.1% and specificity = 33.3%
