The ranges of TG levels in each quartile were: ≤ 0.72 mmol/L (Q1), 0.73–0.96 mmol/L (Q2), 0.97–1.24 mmol/L (Q3), and ≥ 1.25 mmol/L (Q4). Comparisons of continuous data were performed using one-way ANOVA (for LDL-C) or Kruskal-Wallis one-way ANOVA (for age, BMI, HDL-C, TG, glucose, and SBP), and comparisons of categorical data among groups were performed using Pearson’s Chi-square test. ANOVA: analysis of variance; BMI: body mass index; FPG: fasting plasma glucose; HDL-C: high-density lipoprotein cholesterol; LDL-C: low-density lipoprotein cholesterol; N: number; NA: not applicable; SBP: systolic blood pressure; SD: standard deviation; TG: triglycerides; y: year.
