Mean EORTC QLQ-C30 scores of colorectal cancer (CRC) survivors by disease status, and controls. Models are adjusted for age at survey, sex, and education. Disease-free: stage I–III at diagnosis and remaining disease-free at follow-up according to self-report; active disease: stage IV at diagnosis or reported subsequent recurrence, metastasis, or primary cancer. The p-values shown indicate the global comparison between cancer survivors with and without active disease and controls. The line spans and asterisks (*) indicate the subgroups that showed significant differences in pairwise comparison. For example, the line span for global health/QOL is across three columns, indicating that disease-free CRC survivors reported significantly higher global health/QOL when compared with controls. All results are based on 25 imputations of missing values.
