Hemoglobin A1c (HbA1c) is a form of hemoglobin. The HbA1c test is a routine test for people with diabetes. The normal range of HbA1c is less than 6% and measures blood glucose levels over a period of time.
Patients with HbA1c in diabetes range had a significantly higher mortality risk compared to patients with HbA1c in normal range (aHR 1.83 [1.21–2.75], p = 0.004), whereas we did not observe a higher risk for mortality in patients with HbA1c in pre-diabetes range (aHR 1.17 [0.82–1...
Continuous variables were presented as median (interquartile range) or mean ± SD, and categorical data were summarized as frequencies (percentages). Normal distribution of continuous variables was evaluated by Shapiro–Wilk test. For normally distributed variables, differences in tertiles of HbA1c...
