Tables 21[a] and 21[b] show the percent of observed complications by stated duration of diabetes for patients with Type 1 and Type 2 diabetes respectively. The last column calculates the percent of Type 1 and Type 2 individuals respectively, who were found to have each complication. As expected, the occurrence of complications increases with duration, in Type 2 [and particularly in Type 1 for 16+ years], but not so for Proteinuria in Type 1 [note small numbers however – n=3]. Also, most [but not all] of these complications were reported in significant percentages in Type 2 individuals at, or soon after, diagnosis [ie diabetes duration <=18 Mths].
[Please see comments on Diabetes Duration calculation in section 2.7 and section 3].
