Kaplan-Meier estimates of the prognostic impact of SATB1 expression in all patients, and patients with SATB2 negative and positive tumours. Kaplan Meier analysis and log rank test of colorectal cancer specific survival according to negative, intermediate and high SATB1 expression in (A) all patients, (B) patients with SATB2 negative and (C) patients with SATB2 positive tumours. The categories of staining were determined according to the nuclear score (NS), e.g. multiplier of fraction and intensity, whereby negative SATB1 expression = NS 0, intermediate expression = NS 1–3 and strong expression = NS >3.
