Total study population (128 patients) was analyzed for the evaluation of the markers as a diagnostic tool for DM and glucose intolerance
aThreshold value for each diagnostic tool calculated as the nearest point of ROC curve that sensitivity 100 %, false positivity is 0 %
bDM patients were excluded (106 patients were analyzed) for the evaluation of the markers as a diagnostic tool for Prediabetes
