Table 2 Five-year overall Kaplan-Meier survival rates for stratified analysis of chemotherapy group versus control group by high versus low nuclear GST Pi expression in central tumour tissue

From: Glutathione S-transferase Pi expression predicts response to adjuvant chemotherapy for stage C colon cancer: a matched historical control study

  5-year survival rate (95% confidence interval)
Low GST Pi with chemotherapy 68 (55–79)
Low GST Pi without chemotherapy 61 (48–72)
High GST Pi with chemotherapy 69 (52–82)
High GST Pi without chemotherapy 24 (10–42)
