Prevalence of cardiovascular disease (CVD) in 11 categories classified by CKD stages and proteinuria, the CKD-ROUTE study (Oct 2010 - Dec 2011). Odds ratio (OR) was adjusted for age and gender. The reference category is the group with stage 2 and optimal proteinuria. Horizontal lines indicate 95% confidence intervals (95% CI) and the scales are logarithmic. eGFR lower than 30 ml/min per 1.73 m2 and very high proteinuria were significantly associated with the prevalence of CVD.
