Spline curves for outdoor light at night and lipid markers and dyslipidemia. (A) LDL-cholesterol; (B) triglyceride; (C) HDL-cholesterol; (D) total cholesterol; (E) high LDL-cholesterol, high triglyceride, or low HDL-cholesterol; (F) dyslipidemia. In all analyses, participants experiencing the top 1% of LAN were trimmed for the spline model. LAN was fitted as a smooth term using a restricted cubic spline with three knots. Shading indicates 95% CIs. The reference artificial LAN level was 0.2 nW/cm2/sr. Model was adjusted for age, sex, education, smoking status, drinking status, household total income, fine particulate matter, body mass index, fasting glucose, and mutually other lipid markers. LDL-cholesterol, low-density lipoprotein-cholesterol; HDL-cholesterol, high-density lipoprotein-cholesterol.
