From: RIPASA versus Alvarado score in the assessment of suspected appendicitis in children: a prospective study

	Score in (95%CI)
	RIPASA >7.5	Alvarado ≥7	P value
Sensitivity	76.9 (60.7–88.9)	84.6 (72.6–95.7)	0.731
Specificity	87.1 (79.6–91.6)	55.4 (60.9–76.8)	<0.001
PPV	93.1 (87.3–96.8)	95.1 (88.9–98.4)	0.304
NPV	61.2 (46.2–74.8)	44.2(32.8–55.9)	<0.001
Accuracy	84.4 (79.0–89. 7)	73.2(66.7–79.7)	0.803
AUC	0.827 (0.75–0.90)	0.826 (0.74–0.90)	0.970

CI confidence ınterval, PPV positive predictive value, NPV negative predictive value, AUC areas under the curve
