TO THE EDITOR: We thank Dr. Kim for her interest in our paper.1 We agree regarding the issues raised in the correspondence to the editor. The study under discussion was a retrospective analysis of an available serum hemoglobin A1C (HbA1C) level near the performance of a gastric emptying scan. As a result of this limitation, assessment of preprandial or postprandial glucose values as well as duration of diabetes and presence of diabetic complications could not be performed.2-5Categorical analysis of our study patients with abnormal HbA1C (defined as greater than or equal to 7%) and abnormal gastric emptying times (defined as greater than or equal to 120 minutes) showed no statistically significant association (P = 0.525). Because analyses using gastric emptying time and HbA1C as continuous variables did not show conclusive differences, categorical analysis was not performed using cut-off times of 90 or 180 minutes. Further studies prospectively evaluating pre and postprandial glycemia, prolonged gylcemic control measured by multiple serum HbA1C levels over time, age and duration of diabetes diagnosis as well as presence of diabetic complications can further elucidate the relationship of these variables with one another and their effects on gastric emptying time.
