Association between intervention by ESSQS‐qualified surgeons and recurrence‐free survival in patients with stage II and III cancers a Kaplan–Meier analysis of recurrence‐free survival (RFS) in an unadjusted cohort of patients with stage II and III colorectal cancer operated on by ESSQS‐certified or non‐ESSQS‐qualified surgeons. P = 0·221 (log rank test). b,c Cox regression analysis of recurrence. Hazard ratios are shown with 95 per cent confidence intervals for each risk factor for patients with stage II (b) and stage III (c) disease. *P < 0·050. ESSQS, Endoscopic Surgical Skill Qualification System; LND, lymph node dissection; Por, poorly differentiated; Muc, mucinous.
