Nutrient intake is used as the dependent variable, and fibre intake score (FIS) and lactose intake score (LIS) as independent variables in all models.
Note: Confidence intervals (CIs) are presented as lower bound and upper bound.
All models adjusted for age, BMI, Patient-Generated Subjective Global Assessment total score, marital status, smoking habits, diabetes (using living alone, never smoked and no diabetes as reference) and the specific energy and nutrient intakes at baseline.
P-values are considered statistically significant if P < 0.05.
Change from 4 to 8 weeks was calculated as 8 weeks to 4 weeks for nutrients, the FIS and the LIS, respectively.
