ESOPHAGEAL CANCER, DYSPLASIA
Summary statistics for continuous variables (means and standard deviations) and categorical variables (counts and proportions) were presented for both the intervention and control groups. An aggregate of the compliance for all 12 weeks for each individual was obtained by dividing 100/12 for example, 100% compliance if patients have full compliance for all 12 weeks, 92% if they have missed 1 week, 83% if missed 2 weeks, etc, and presented as mean.All available data were included in the statistical analysis referring to the intention‐to‐treat approach with respect to the original study group assignment and regardless of the patient's participation rate in the exercise intervention. Complete case analysis was used and no attempt to impute missing data was made. Changes in muscle strength and muscle mass were assessed as continuous outcomes. Mean differences (MD) with 95% confidence intervals (CI) were calculated to compare changes between baseline and post‐intervention assessments for the two groups. Owing to limited sample size, randomization might not be sufficient to control for confounding. Therefore, three models were used. In model 1, no confounders were adjusted for, and independent Baseline characteristics of study participants in a Swedish nationwide randomized controlled trial of a home‐based physical activity program in patients treated with surgery for esophageal cancer
