Performance of PIM, PRISM, and PELOD scores in a resource-limited North Indian paediatric intensive care unit

Table 2 Comparison of pediatric risk of mortality score III, pediatric index of mortality-3, and pediatric logistic organ dysfunction score-2 mortality scores between survivors and non-survivors, mean ± SD/median (interquartile range)

	Survivors, n = 151	Non survivors, n = 24	Total, n = 175	P value	AUROC (95%CI)	Observed death (O)	Expected death (E)	SMR (O/E) 95%CI	Calibration HL-GOF
PRISM-III	4.35 ± 3.92	13.04 ± 7.68	5.54 ± 5.55	< 0.001	0.884 (0.827-0.927)	24	23	1.04 (0.63-0.46)	χ2 = 2.69, P = 0.952

HL-GOF: Hosmer-Lemeshow goodness of fit; AUROC: Area under the receiver operating characteristic curve; CI: Confidence interval; SMR: Standardized mortality ratio; PELOD-2: Pediatric logistic organ dysfunction score-2; PRISM-III: Pediatric risk of mortality score III; PIM-3: Pediatric index of mortality-3.
