The subjects also underwent an oral glucose-tolerance test and an intravenous insulin-tolerance test.

受试者同样需要进行口服糖耐量测试和静脉内胰岛素耐量测试。

Every group was divided into normal glucose tolerance subgroup (NGT) and impaired glucose tolerance subgroup (IGT) according to oral glucose tolerance test.

根据口服葡萄糖耐量试验将每组分为正常糖耐量亚组（NGT）和糖耐量减低亚组（IGT）。

Impaired glucose tolerance (IGT) means that blood glucose during the oral glucose tolerance test is higher than normal but not high enough for a diagnosis of diabetes.

糖耐量受损（IGT）是指，在口服糖耐受量试剂时血糖高于正常，但还未达到糖尿病的诊断标准。
