Context

Anaemia frequency and severity worsen with advancing chronic kidney disease (CKD) and are associated with quality-of-life (QOL) impairment, morbidity and mortality.1 Deficient renal erythropoietin production is a major cause and can be corrected by recombinant human erythropoietin (rhEPO) administration.1 This may improve clinical outcomes, including delaying dialysis. Conversely, rhEPO therapy causes hypertension,2 thereby potentially accelerating CKD progression. This systematic review and meta-analysis examined rhEPO effects on clinical outcomes in anaemic, pre-dialysis CKD patients.

Methods

Randomised controlled trials (RCTs) comparing rhEPO treatment with either placebo …
