SD standard deviation
aTesting differences in characteristics between included and not included eligible colorectal cancer survivors if data were available for both groups; by Pearson’s Chi-square test for most categorical variables (gender, tumor subsite, tumor stage, and treatment with radiotherapy and chemotherapy), Fisher’s exact test for treatment with surgery (due to expected frequency below 5 in one cell), and independent t test for continuous variables (age and years since diagnosis)
bData missing for 16 cases (eight included and eight excluded survivors)
cData missing for one participant; dichotomized based on six-item Social Support List score (scale: 6–18, with higher score indicating higher deficiency); categorized into no deficiency (score = 6) vs deficiency (score > 6)
