Figure 1 Flow chart of study participants. ∗Essential data: age; sex; systolic blood pressure; diastolic blood pressure; levels of hemoglobin A1c, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides; waist circumference; information on smoking, alcohol consumption, and exercise habits; histories of stroke and heart disease; and medication for hypertension, diabetes mellitus, and dyslipidemia. Abbreviations: CKD, chronic kidney disease; eGFR, estimated glomerular filtration rate.

Figure 2 Change in estimated glomerular filtration rate (eGFR) according to quartile (Q) of triglycerides to high-density lipoprotein cholesterol (TG:HDL-C) ratio (results of study 1). The 2-year changes in eGFR according to quartiles of TG:HDL-C ratio based on (A) baseline eGFR-adjusted and (B) multivariable-adjusted regression models are shown. Each bar represents the least square mean of the change in eGFR during the 2-year study period (eGFR at 2 years minus eGFR at baseline) and each vertical line represents the standard error of the mean.

Figure 3 Change in estimated glomerular filtration rate (eGFR) according to quartile (Q) of triglycerides to high-density lipoprotein cholesterol (TG:HDL-C) ratio stratified by various variables (results of study 1). The 2-year changes in the eGFR based on a multivariable-adjusted regression model stratified by (A) sex, (B) diabetes mellitus, (C) hypertension, and (D) obesity are shown. Each bar represents the least square mean of the change in eGFR during the 2-year study period (eGFR at 2 years minus eGFR at baseline) and each vertical line represents the standard error of the mean.

Figure 4 Odds ratio for incident chronic kidney disease (CKD) according to quartile (Q) of triglyceride to high-density lipoprotein cholesterol (TG:HDL-C) ratio stratified by various variables (results of study 2). Odds ratios for incident CKD according to the quartile of TG:HDL-C ratio stratified by sex, diabetes mellitus, hypertension, and obesity are shown.
