Figure 2. Association between Estimated Baseline GFR and CHD Adjusted for Age, Sex, Period, Smoking Status, and Other Established Risk Factors.

eGFR was calculated using Modification of Diet in Renal Disease equation. The size of the data markers is proportional to the inverse of the variance of the ORs. 95% CIs are calculated using floating-variance. Established risk factors included total cholesterol, triglycerides (log transformed), systolic blood pressure, and BMI. eGFR_MDRD, overall χ ² with 6 df = 14.6, p = 0.02.
