Endoscopic findings in patients with upper gastrointestinal bleeding clinically classified into three risk groups prior to endoscopy

Table 1 Numerical values for each parameter of the clinical index adopted in the study

Clinical parameter	Score
	1	2	3
General conditions	Poor	Intermediate	Good
Pulse (beats/min)	> 110	90-110	< 90
Systolic blood pressure (mmHg)	< 90	90-110	> 110
Haemoglobin levels (g/dL)	≤ 8	9-10	> 10

The T-score is the sum of the corresponding values for the 4 parameters. In detail, a sum ≤ 6 corresponds to T1 (high-risk), 7-9 to T2 (intermediate-risk), and a cumulative value ≥ 10 to T3 (low-risk).
