Receiver operating characteristic curve showed that the model comprising of baseline fasting plasma glucose ( FPG ) and GGT ( area-under-curve ( AUC ) -LSB- @ % CI -RSB- : @ -LSB- @-@ @ -RSB- ; P < @ ) was equally sensitive in identifying subjects with risk of diabetes as compared to @ hr PG ( AUC -LSB- @ % CI -RSB- : @ -LSB- @-@ @ -RSB- ; P < @ ) and HbA@c ( AUC -LSB- @ % CI -RSB- : @ -LSB- @-@ @ -RSB- ; P < @ ) alone .
