Association between cardiorespiratory fitness and impaired vascular function in type 2 diabetes

Table 3 Association between cardiorespiratory fitness and the odds of impaired vascular function

Variable	No. of cases/total	Model 1		Model 2		Model 3
		OR (95%CI)	P value	OR (95%CI)	P value	OR (95%CI)	P value
CRF tertiles (MET)
Lowest (< 5.2)	42/117	1 (reference)		1 (reference)		1 (reference)
Middle (5.2-6.2)	29/119	0.58 (0.33-1.01)	0.06	0.73 (0.40-1.35)	0.32	0.68 (0.35-1.32)	0.25
Highest (> 6.2)	17/107	0.34 (0.18-0.64)	0.001	0.48 (0.24-0.98)	0.04	0.44 (0.20-0.96)	0.04
Per 1-MET increase	88/343	0.69 (0.57-0.84)	< 0.001	0.75 (0.61-0.94)	0.01	0.73 (0.57-0.93)	0.01

Model 1 was a crude model. Model 2 was adjusted for age and gender. Model 3 was adjusted for age, gender, history of smoking and drinking, systolic blood pressure, body mass index, estimated glomerular filtration rate, high-density lipoprotein-cholesterol, triglycerides, and hemoglobin A1c. CRF: Cardiorespiratory fitness; MET: Metabolic equivalent; OR: Odds ratio; CI: Confidence interval.
