Updated New Zealand cardiovascular disease risk-benefit prediction guide

The legend above the risk prediction chart in this article by Rodney Jackson (11 March, pp 709-10) has a small error. In the right hand column (“Benefit 2”) the final number needed to treat (at the <2.5% risk level) should be 120 [not 20]. We are sorry for the delay in alerting readers to this, although in the context, confusion was unlikely.
