Note: CI = confidence interval, CV = coefficient of variation.
↵* The slope term indicates the annual change in the CV and the Gini coefficient of the number of days until first treatment for each cancer–treatment type pair. For example, among patients with colorectal cancer who received chemotherapy as their first treatment, the CV of the time to first treatment decreased by 0.06 per year over the study period.
