		HC (n = 45)	T1C(n = 9)	WFS (n = 11)
Gender	M/F	23/22	7/2	5/6
Age in years	Mean	11.9±3.1	11.8±2.3	14.0±6.3
	Range	7.0–17.7	7.1–14.2	5.9–25.8
Duration of diabetes in years	Mean	–	.19±.05	7.4±5.3
	Range	–	.11–.25	.75–16.2

Abbreviation. HC: healthy controls; T1C: diabetic controls; WFS: Wolfram Syndrome group; SD: standard deviation.

There were no differences between groups for age (p = .24) or gender (p = .28) but there was a significant. difference in duration of diabetes between T1C and WFS (p = .001).
