PURPOSE The triglycerides to high-density lipoprotein cholesterol (TG/HDL-C) ratio could be related to insulin resistance (IR). We previously reported that Korean women with polycystic ovary syndrome (PCOS) had a high prevalence of impaired glucose tolerance (IGT). We aimed to determine the cutoff value of the TG/HDL-C ratio for predicting IR and to examine whether the TG/HDL-C ratio is useful ...

The analysis results of KNHANES data are usually presented as weighted mean±standard error of mean (SEM) or weighted proportion (SE). The reason for providing standard error instead of standard deviation is attributed to the fact that standard deviation only describes variation of sample data. On the other hand, standard error provides the precision of estimate (weighted mean/weight proportion)...
