  1. aOther/Unknown were combined due to cell sizes of ≤1% in both, reported combined with Operation due to small cell sizes; Other includes autopsy, cytology, judgmental, and x-ray; bUnknown accounts for < 1%, reported combined due to small cell sizes; cOther tumour location is < 1%; dStage 0 was combined with stage I due to cell sizes < 1%; eData available on 24,155 CRC patients; SPI = severe psychiatric illness; Kruskall-Wallis tests for skewed continuous data and Chi-square tests for independence for categorical variables were used to investigate the relationship between severe psychiatric illness history status and demographic and cancer characteristics. Cells with Pearson residual values ≥3 contributed most significantly to the lack of independence between demographic characteristics and an SPI history and are highlighted with bold font type
