Table 2. Test characteristics of EDSC against ASQ, having “EDSC Delay” as tool positive.

Criteria of test positive	Child delayed in EDSC taken “EDSC delay” (Tool positive)
Sensitivitya	84.38 (95% CI [67.21%–94.72%])
Specificityb	98.36 (95% CI [96.22%–99.47%])
Positive Predictive Valuec	84.38 (95% CI [69.09%–92.88%])
Negative Predictive valued	98.36 (95% CI [96.41%–99.26%])
Overall Test Accuracye	97.03 (95% CI [94.61%–98.57%]) (p ≤ .001)
Proportions of specific agreement:
Negative agreement	= 2 * 300 / (2*300 + 5 +5) = 98.36%
Positive agreement	= 2 * 27 / (2*27 + 5 +5) = 84.38%

Notes.

^aSensitivity: probability that a test result will be positive when the disease is present (true positive rate).

^bSpecificity: probability that a test result will be negative when the disease is not present (true negative rate).

^cPositive predictive value: probability that the disease is present when the test is positive.

^dNegative predictive value: probability that the disease is not present when the test is negative.

^eAccuracy: overall probability that a patient is correctly classified.
