Association Between Postoperative Platelet-to-Hemoglobin Ratio Trajectories and Acute Kidney Injury in Patients Undergoing Cardiac Surgery: A Retrospective Cohort Study with External Validation

Paper C Not peer reviewed Observational

Key takeaways

This study looked back at patients who had heart surgery and tracked how their platelet count compared with their hemoglobin over the following days. Certain patterns in that ratio lined up with sudden kidney injury after surgery. The findings were checked against a second, separate group of patients, which makes the pattern more believable. It shows a link only, not cause, and this is a preprint that has not been through peer review.
