Bottom Line: The difference between self-reported and GP-confirmed age at diagnosis was analysed with a Bland-Altman plot.Completed questionnaires were obtained from 157 GPs (91.2%).The average difference between self-reported and GP-reported age at diagnosis was 0.6 years (95% CI 0.2-1.1).

Differences in years between self-reported and GP-confirmed age at diagnosis plotted against the average difference. Horizontal lines denote the mean difference (0.6 years), and the upper (5.1 years) and lower (−3.7 years) limits of agreement (mean difference ± 1.96 SD of the differences).

fig0005: Differences in years between self-reported and GP-confirmed age at diagnosis plotted against the average difference. Horizontal lines denote the mean difference (0.6 years), and the upper (5.1 years) and lower (−3.7 years) limits of agreement (mean difference ± 1.96 SD of the differences).

Mentions: The date of diagnosis was reported by 148 GPs. The mean age at diagnosis was 55.5 years (±SD 7.3). Information on self-reported age at diagnosis was available for 102 study members. Of these, 37 (36.2%) reported the same age in years at diagnosis as their GP. Fig. 1 plots the differences between self-reported and GP-reported age at diagnosis against the average difference. The average difference was 0.6 years (95% CI 0.2–1.1). The 95% limits of agreements were 5.1/−3.7 years. Information on treatment was reported by 148 GPs. The combination of diet and oral hypoglycaemic agents was the most common treatment prescribed (37.1%) followed by oral hypoglycaemic agents alone (31%) and diet alone (15.5%). Twenty-four (16.2%) study members were treated with insulin.
