Quality-of-care indicators, including number of lymph nodes removed, anastomotic leak rate, 30- and 90-day mortality, and 2- and 5-year overall survival, were assessed. To compare quality-of-care indicators over time, the relative risk (RR) was calculated using a multivariable log binomial regression model.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Some 6178 patients were included, of whom 1728 underwent oesophagectomy. The overall number of patients with 15 or more lymph nodes in the resection specimen increased from 38\u00b71 per cent in 2004 to 88\u00b77 per cent in 2013. The anastomotic leak rate decreased from 14\u00b78 to 7\u00b76 per cent (RR 0\u00b766, 95 per cent c.i. 0\u00b743 to 1\u00b701).
