Fig. 2. Time intervals (days) from symptomatic primary care presentation to cancer diagnosis.
Values are shown for colon (top row) and rectal cancer (bottom row) patients by Charlson comorbidity Index (CCI) score. Solid line CCI score 0; dashed line CCI score 1; dotted line CCI score 2; large dashed line CCI score 3+. Symptom to test and test to diagnosis intervals refer to the subgroup of patients with a relevant test (n = 2301 colon; n = 1390 rectum), while the symptom to diagnosis intervals refer to the total sample (n = 3215 colon; n = 1621 rectum). The symptom-to-diagnosis interval for the subgroup of tested individuals is shown Supplementary Fig. 1. Note: The median values shown here are statistically significantly different (p < 0.001) when comparing patients with Charlson score 1+ versus 0.
