Balthazar computed tomography severity index is superior to Ranson criteria and APACHE II scoring system in predicting acute pancreatitis outcome

Table 1 The comparison of severity, complication, mortality, and the length of stay in CTSI, Ranson score, and APACHE II score

Mortality	Present	5.3±1.7	2.3±0.5	7.3±1.3
	Absent	1.8±0.61	2.5±0.7	8.5±0.9
