A serial mediation analysis of preoperative anemia, postoperative anemia burden, and RBC transfusion on AKI risk in cardiac surgery

Key takeaways

This study looked at 44,810 people having heart surgery. It checked if low blood counts before surgery led to kidney injury. The results show a link between low blood counts and kidney problems. This is a link, not proof of cause, but it helps doctors watch for risk.
