Association between Plasma Homocysteine Concentrations and the First Ischemic Stroke in Hypertensive Patients with Obstructive Sleep Apnea: A 7-Year Retrospective Cohort Study from China

Figure 3

A piecewise linear regression model was used to detect the association of plasma Hcy concentrations and the first IS according to the plasma Hcy concentration cut points. All were adjusted for age, gender, smoking status, drinking status, NC, WC, BMI, SBP, DBP, history of arrhythmia, diabetes, AHI, AI, HI, sleep duration, mean SaO₂ and lowest SaO₂, antidiabetic drugs, antiplatelet drugs, lipid-lowering drugs, regular CPAP treatment, antihypertensive drugs, and TC, TG, HDL-c, LDL-c, FPG, eGFR, Cr, and hs-CRP levels at baseline.
