Data are means ± SD or percent.
Entered as explanatory variable in exploratory regression analyses with cognition or MRI as dependent variables within the type 1 diabetic group; statistically significant association with any cognitive domain scores are indicated as
P < 0.05; statistically significant association with any MRI outcome measure are indicated as
P < 0.05. Details are provided in results.
In the regression analyses, the group that experienced hypoglycemia with seizure or unconsciousness was compared with the group that never experienced any severe hypoglycemic event.
Microvascular complications were entered in the exploratory regression analyses in two ways: as a dichotomous variable defined as the absence or presence of retinopathy or neuropathy or as a sumscore (range 0–3) in which 1 point was given for neuropathy, 1 point for retinopathy without laser treatment, or 2 points for retinopathy with laser treatment. Neither analysis showed significant associations with MRI or cognition.
