How do we report the proportion of patients undergoing colonic resection reported as having more than 12 lymph nodes examined in the 2019 report?

All colon cancer patients aged 18 or over diagnosed between 1 April 2017 and 31 March 2018 who, according to NBOCA, underwent a major resection (regardless of surgical urgency or curative intent).

We then report on the proportion of those patients identified above with >=12 lymph nodes reported.
