Sensitivity and specificity of the weighted score above different score cut points (summed weightings) as applied to Agincourt data and tested against study physician classification of cases

Cut point	Number of deaths above cut point	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)
5	169	83.54	98.91	39.05	99.85
6	138	82.27	99.15	47.10	99.84

8	134	82.28	99.20	48.01	99.84
9	133	81.01	99.20	48.12	99.82

NPV, negative predictive value; PPV, positive predictive value.
