Table 3. Hospital stay and mortality rates according to serum albumin groups.

Variable	Low albumin (n=51)	Normal albumin (n=406)	P value
Hospital stay (days)	12 (9; 16)	9 (8; 12)	<0.001
Intensive care unit stay (days)	4 (2; 5)	3 (1; 4)	0.001
Immediate procedural mortality	0 [0]	5 [1.2]	1*
In-hospital mortality	4 [8]	12 [3]	0.093*
30-day mortality	5 [10]	14 [3]	0.045*

Data presented as number [percentage] for categorical variables, mean standard deviation for normally distributed or median and (25^th and 75^th percentile) for not normally distributed continuous variables. Accordingly, Chi-square, exact Fisher*, Student’s t-test or Mann-Whitney U test were used to compare.
