Strongest correlation of HbA(1c) with 1-month-earlier glucose levels in type 2 diabetes

We examined the correlations of hemoglobin A(1c) (HbA(1c)) with each plasma glucose (PG) level obtained at 0 (the same day), 1 and 2 month(s) prior to HbA(1c) determination. Data were from glycemic profiles of four patients of type 2 diabetes mellitus treated with tablets whose HbA(1c) and pre- and...

Description
Summary:We examined the correlations of hemoglobin A(1c) (HbA(1c)) with each plasma glucose (PG) level obtained at 0 (the same day), 1 and 2 month(s) prior to HbA(1c) determination. Data were from glycemic profiles of four patients of type 2 diabetes mellitus treated with tablets whose HbA(1c) and pre- and post-breakfast PG levels were monitored each month. There was no significant difference in the correlation coefficients in cases 1 and 2, who presented with linear glycemic time courses. In contrast, HbA(1c) correlated with 1-month-earlier pre-breakfast PG level more strongly than 2-month-earlier post-breakfast PG level in cases 3 and 4, and than same-day post-breakfast PG level in case 3 (P
