Abbreviations: ref., reference category; CCI, Charlson comorbidity index; NRS-2002, nutrition risk screening 2002. Analyses were performed among patients with NRS-2002≥3, first-prealbumin levels<0.2 g/l and length of hospital stay ≥10 days (n = 346/439). Results are presented as OR (95% CI). Bivariate analysis performed using logistic regression in which adherence to the guideline (yes or no) was the outcome and each characteristic was the predictor; multivariable analysis performed using logistic regression adjusting for all variables in the table.
* P-values for trend are computed using orthogonal polynomial contrasts (command contrast p. of Stata).
