Figure 1.

Oxalate concentrations and the risk of mortality/cardiovascular events in 1108 patients (4D Study cohort) with kidney failure requiring chronic HD (Forest plot). Multivariable-adjusted HRs and 95% CIs (error bars) for all-cause mortality, combined cardiovascular events, sudden cardiac death, death due to heart failure, myocardial infarction, and stroke in the 4D Study cohort stratified by oxalate concentrations at baseline (quartiles). Models are adjusted for age, sex, use of atorvastatin, time on HD, use of diuretics, C-reactive protein, body mass index, hemoglobin, albumin, and previous coronary artery disease (core model).
