Numbers of patients studied, classified according to type of diabetes and gender. The numbers of patients identified by each source (hospital, primary care or identified in both) are given with the capture-recapture estimate generated and the total in in each category obtained by source linkage. As the number of patients whose type of diabetes was unclassified was small (3.3% of the total) these have been included with the type 2 patients
