↵a Specialism responses indicate proportions indicating they had a special interest in that field. Therefore figures do not compute to 100%. Note: all GPs from Scotland were randomised to the ‘high risk, GP prescriber’ condition, as per the national guideline in that country. They were not included in these analyses.
