Figure 1: Characteristics of PR, A1C at diagnosis and during follow-up. (a) Box plots with ranges showing no difference in PR duration between gender and age subgroups. [+] shows means for each group. (b) Distribution of PR durations among remitters (). (c) Evolution of A1C levels during follow-up. (d) A1C levels at diagnosis among gender and age subgroups. (e) Graphs showing correlation between PR duration and A1C levels 2, 3, and 5 years after follow-up (resp., A1C+2y, A1C+3y, and A1C+5y). PR durations were grouped to correspond to 3 months ± 15 days and 6, 9, 12, and 18 months ± 30 days. All bars were shown with SEM. , , and compared with indicated groups.
