Table 4

Univariate and multivariate analyses for the prognostic value of sex at premenopausal age stratified by race.

American Indian/Alaska Native (56 (1.1))	0.94	0.94 (0.22–4.02)	0.99	1.00 (0.16–6.25)

Significant value. Abbreviation: TNM: tumour-node-metastasis. ^§Sex differences of prognosis were adjusted by tumour location (colon/rectum), grade (well differentiated/moderately differentiated/poorly differentiated or undifferentiated), TNM stage (0/I/II/III/IV), insurance status (insured/others), marital status (married/widowed/others) and surgery for primary tumours (no/yes) in multivariate analysis.
