In an effort to find predictors of EGPclamp variation, we performed simple correlations between EGPclamp and parameters which could influence EGPclamp. The following parameters correlated to EGPclamp with a p-value <0.1: diabetes duration, fasting plasma glucose (FPG), se-insulin at end of clamp, fasting se-C-peptide and HbA1c (Table 5). Here, INS is linked to diabetes mellitus.
