From: The influence of different glucose tolerance on QTc interval: a population-based study
Adjusted means (± SD) of QTc interval in subjects with NGR, IGR (isolated IFG, isolated IGT), combined IFG/IGT and diabetes mellitus (DM). Subjects with type 2 diabetes mellitus and IGR (isolated IFG, isolated IGT and IFG/IGT) had higher level of QTc interval than those with NGR (both p < 0.0001). There was no significant difference among the subgroups of IGR (p = 0.35) and between the IGR and type 2 diabetes mellitus groups (p = 0.61)
