Similar to the GA/HbA1c ratio, the GA correlated with BMI (r = −0.16, p < 0.0001), age (r = −0.20, p < 0.0001), haemoglobin level (r = −0.12, p < 0.005), the duration of diabetes (r = 0.21, p < 0.0001), diastolic BP (r = −0.15, p < 0.0005) and the serum albumin level (r = −0.16, p < 0.0005). Here, ALB is linked to diabetes mellitus.
