The combined prevalence of moderate and severe malnutrition was 27.2%. Hypovitaminosis C was present in 64 patients (36.8%) and was associated with an increased likelihood of a complication on both univariate (OR 1.9 [1.01\u20133.51; 95% CI]) and multivariate (OR 2.2 [1.12\u20134.29; 95% CI]) analysis. On further subgroup univariate analysis, increased age, hypertension, macrocytosis, PG\u2010SGA score and moderate malnutrition were associated with postoperative medical complications.
