The association between baseline plasma selenium and first total stroke and first ischemic stroke risks. Odds ratios for first total stroke in the (A) total population, (C) males, and (E) females, and for first ischemic stroke in the (B) total population, (D) males, and (F) females by plasma selenium levels. In addition to the matching factors (age and sex), the splines also adjusted for BMI, baseline SBP, baseline DBP, smoking status, alcohol consumption, labor intensity, baseline total homocysteine, vitamin E, fasting glucose, estimated glomerular filtration rate (eGFR), anti-platelet drugs, lipoprotein-lowering drugs, glucose-lowering drugs, anti-hypertensive drugs, self-reported hypertension, self-reported diabetes, self-reported atrial fibrillation, and self-reported hyperlipidemia
