The only way that the claims of the McEvoy study could match the data on Figure 3, is that their key info, is incorrect. In this case the black circles would represent the Irish data and the White ones the 8,000 plus individuals of the comparative sample. However, clearly this is not what the key says. The problem is the value (n=?) of the individual circles is not displayed so there is no way of checking this, short of contacting the authors.
