Erratum to: Typologies in GPs' referral practice

The original article contained a major omission whereby Tables 1, 2, 3, 4 were mistakenly left out from the article body; this error was carried forward by the production team handling this article, and thus was not the fault of the authors. As such, the original article has now been updated to include these tables.
