Table 8 Value of indicators in predicting PICU mortality

	Cut-off point	AUC	Sensitivity	Specificity	+PV	− PV
rT3 (ng/dl) day 1	> 200	0.724	47.62	94.74	90.9	62.1
SOFA score day 1	> 6	0.779	76.19	68.42	72.7	72.2
FT3 (pg/ml) day 5	≤ 2.08	0.847	100.00	68.42	64.7	100.0
rT3 (ng/dl) day 5	> 270	0.835	81.82	78.95	69.2	88.2
CRP day 5	> 57	0.751	81.82	68.42	60.0	86.7
SOFA score day 5	> 3	0.837	100.00	57.89	57.9	100.0

The cut-off value of FT3 in day 5 was ≤ 2.08 Pg/ml which gives sensitivity 100% and specificity 68.42%. And show the cut-off value of SOFA score day 5 was > 3 which gives sensitivity 100% and specificity 57.49%
