Time to liver surgery and age‐standardized relative survival a Time to liver surgery from diagnosis of liver metastases (median 5·0 months) and colorectal cancer (median 9·1 months). b Age‐standardized relative survival grouped by quartiles of time between diagnosis of colorectal cancer and liver surgery: quartile (Q) 1, 0–0·46 years (330 patients); Q2, 0·46–0·76 years (328 patients); Q3, 0·76–1·54 years (335 patients); Q4, 1·54–7·12 years (332 patients). The excess mortality rate ratio for Q3 versus Q4 was 1·44 (95 per cent c.i. 1·12 to 1·86). b P = 0·044 (Wald test).
