Variables with p <0.25 were used in the multivariate analysis (indicated in bold) a ACE-27 = Adult Comorbidity Evaluation-27, b ASA classification = American Society of Anesthesiologists physical status classification system, c Hb = hemoglobin, d BMI = Body Mass Index LENGTH OF HOSPITAL STAY The univariate linear regression analysis with potential risk factors for length of hospital stay yielded six variables with p values less than 0.25: ACE-27 [score 2 (OR = 1.09)], ASA [score 3+ (OR = 1.10)], alcohol use [>3U/day (OR = 1.06)], operating time (OR = 1.05), decrease in hemo - globin level (OR = 1.106) and BMI (OR=1.0) (Table 5). These six variables, and sarcopenia, were entered in the multivariate analysis for length of hospital stay. Table 5.
