Erythropoiesis‐stimulating agents as replacement therapy for blood transfusions in critically ill patients with anaemia: A systematic review with meta‐analysis

ESA resulted in a small reduction in the proportion of patients transfused and a trivial increase in haemoglobin concentration, both of questionable clinical relevance, without impacting adverse events or mortality. These results do not support the routine use of ESA to treat anaemia in critically ill adults.
