Preoperative Hypoalbuminemia as an Independent Predictor of Postoperative Acute Kidney Dysfunction After Cardiac Surgery.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Postoperative acute renal failure associated with mortality after cardiac surgery. Whereas many variables result in postoperative renal failure, current literature lacks commentary on preoperative serum albumin optimization. Methods: We performed a retrospective review of a single adult cardiac surgery center database between 2021 and 2024. Patients were divided into 2 cohorts: preoperative hypoalbuminemia (<3.5 g/dL) and normal albuminemia (3.5-5.4 g/dL). Demographic and clinical characteristics were compared. The primary outcome was kidney injury or kidney failure, defined by the RIFLE (risk, injury, failure, loss of kidney function, end-stage kidney disease) criteria. Multivariable logistic regression evaluated the association of preoperative albumin level and postoperative kidney dysfunction. Results: There were 1673 patients who underwent cardiac surgery during 4 years, 444 (27%) with hypoalbuminemia and 1229 (63%) with normal albuminemia. The hypoalbuminemia group was younger (63 vs 65 years; Conclusions: Hypoalbuminemia is significantly associated with postoperative acute kidney dysfunction in cardiac surgery patients. Preoperative optimization may decrease the risk of renal complications.
