Table 3. Adjusted HR and 95% CIs for the cancer incidence according to HbA1c level.

All site cancer	HbA1c, %
	< 5.7 (n = 4,663)	≥ 5.7 and < 6.5 (n = 2,840)	≥ 6.5 (n = 319)
Unadjusted	1.00 (ref.)	0.86 (0.56–1.33)	2.98 (1.61–5.52)
Multivariate-adjusted*	1.00 (ref.)	0.80 (0.52–1.25)	2.70 (1.43–5.09)
Multivariate-adjusted†	1.00 (ref.)	0.77 (0.48–1.23)	3.03 (1.54–5.96)

HR, hazard ratio; CI, confidence interval; HbA1c, hemoglobin A1c; BMI, body mass index.
