Fig. 2. Box-plots summarizing the absolute differences (%HbA1c and mmol/mol HbA1c) between each test method and the comparison method for HbAA, HbAC, HbAD, HbAE and HbAS.

Fig. 2.

The horizontal line in each box is the median difference between the test and comparison methods. The limits of each box correspond to the 25th and 75th percentiles of the differences. The highest and lowest horizontal bars represent the most extreme individual differences between the test and comparison methods. Differences from HbAA that are statistically significant are indicated (#) below each bar where appropriate; clinically significant differences are indicated (*) above each bar where appropriate.
