Multiple linear regression models for corrected QT interval

Model	Variables	β coefficient	t‐value	P‐value
1	Neuropathy	3.06	2.14	0.034
2	Retinopathy	1.90	1.03	0.30
3	Nephropathy	4.63	3.16	0.0018
4	Multiplicity of microvascular complications	4.60	3.10	0.0022

Data are expressed as β coefficient (estimated partial regression coefficient), t and P values for the association of corrected QT interval with microvascular complications (neuropathy [model 1], retinopathy [model 2], nephropathy [model 3] and multiplicity of microvascular complications [model 4]) and clinical covariates (age, sex, duration of diabetes, body mass index, systolic blood pressure and insulin therapy).
