Dr Icks et al raise a number of issues pertaining to our recently published article. First, in contrast with our findings, they propose that only nausea and incontinence are more common in pepole with diabetes compared with nondiabetic controls. Their conclusion is based on a study of subjects with diabetes selected from a diabetes register compared with 544 control subjects. Unfortunately, Icks et al did not detail how the control subjects were recruited: were they population controls or nondiabetic patients from outpatient clinics or from primary care practices? More important, subjects with diabetes and nondiabetic controls were not exposed to the same method of data sampling, as only diabetic subjects were assessed clinically, and this may have introduced bias. One of the strengths of our study is the recruitment of both diabetic subjects and nondiabetic controls from the same population-based sample.
