Gastrointestinal symptom prevalence depends on disease duration and gastrointestinal region in type 2 diabetes mellitus

Figure 1 Distribution of the sum of scores of symptoms related to all GI areas by duration of diabetes. ^aP < 0.05, significantly different. Sums of symptom scores peaked during the 15- to 19-yr diabetes duration period, compared by Student’s t-tests for paired periods (P = 0.01 and P = 0.02 when compared with 5-9 yr and 10-14 yr disease durations, respectively).
