Prevalence of increased QTc interval duration and QTc dispersion in patients with type 2 diabetes

	Males (n = 277)	Females (n = 224)	Total (n = 501)
Increased QTc duration (>440 ms)	35.7 (28.2–39.1)	54.5 (46.0–61.2)*	44.1 (39.6–52.4)
Increased QTc duration (≥500 ms)	0.7 (0.4–1.1)	3.5 (2.7–4.6)*	2.0 (1.6–2.4)
Increased QTc dispersion (>80 ms)	2.9 (2.3–3.3)	4.5 (3.7–5.1)*	3.6 (3.0–4.1)

Values are given as % (95 % CI)
