Multiple regression analysis was performed with the constipation scoring system (CSS) score as the dependent variable, and with age, sex, BMI, laxative/prokinetics use, sarcopenia, albumin level, cholesterol level, lymphocyte count, CONUT score, reflux-related QOL score, upper abdominal pain-related QOL score, fullness-related QOL score, constipation-related QOL score, diarrhea-related QOL score, and BSFS score as independent variables. B, partial regression coefficient; SE, standard error; CI, confidence interval; β, standardized partial regression coefficient; t, t-ratio; VIF, variance inflation factor; CONUT, CONtrolling NUTritional status; BSFS, Bristol Stool Form Scale; BMI, body mass index; QOL, quality of life.
