QT prolongation is associated with increased mortality in end stage liver disease

Table 2 Estimated odds ratios for mortality based on levels of QT_c prolongation

	OR	P	95%CI
Mild QTc prolongation vs none	1.67	0.045	1.01-2.76
Moderate QTc prolongation vs none	2.11	0.013	1.17-3.81
Severe QTc prolongation vs none	1.83	0.044	1.02-3.31

Mild QT_c prolongation: 451-470 ms in males and 471-490 ms in females; Moderate QT_c prolongation: 471-490 ms in males and 491-510 ms in females; Severe QT_c prolongation: > 490 ms in males and > 510 ms in females.
