Table 4

The best 5 cut-offs of each laboratory data for predicting rebleeding.

	5th	4th	3rd	2nd	1st
HB (g/L)	74	84	77	86	73
Youden’s index	0.333	0.333	0.336	0.342	0.345
BUN (mmol/L)	11.9	9.7	9.3	9.8	9.4
Youden’s index	0.254	0.257	0.260	0.263	0.272
Scr (μmol/L)	94	95	99	100	102
Youden’s index	0.281	0.287	0.287	0.292	0.295

HB: hemoglobin; BUN: blood urea nitrogen; Scr: serum creatinine; Youden’s index: sensitivity + specificity − 1.
