Abbreviations: V/S: Visceral/subcutaneous (fat volume ratio), ACCI: Age-adjusted Charlson comorbidity index. Footnotes: Data from the overall cohort are presented as beta coefficients (i.e., the median difference in PMV between each post-pancreatitis group and healthy controls group) and standard errors, from linear regression models. Statistically significant (p < 0.05) differences are shown in bold. Model 1: Unadjusted model; Model 2: Adjusted for age and sex; Model 3: Adjusted for age, sex, V/S fat volume ratio, and physical activity; Model 4: Adjusted for age, sex, V/S fat volume ratio, physical activity, smoking status, and alcohol consumption; Model 5: Adjusted for age, sex, V/S fat volume ratio, physical activity, smoking status, alcohol consumption, ACCI, pancreatic amylase, and use of insulin. Statistically significant (p < 0.05) associations are shown in bold.
