Preoperative Uric Acid-to-Albumin Ratio as a Predictor of Postoperative Atrial Fibrillation After Cardiac Surgery.
Article in Brazilian journal of cardiovascular surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionPostoperative atrial fibrillation (POAF), the pathophysiology that includes inflammation and oxidative stress, is associated with increased hospital length of stay, mortality, and complications. The uric acid-to-albumin ratio reflects the inflammatory status of the body. We sought to evaluate whether there is an association between POAF and uric acid-to-albumin ratio in patients undergoing cardiac surgery.
methodsFive hundred forty-three patients who developed POAF and 166 patients who did not formed our control and study groups, respectively. Patients who had an episode of atrial fibrillation lasting > 30 seconds were considered to have POAF. The uric acid-to-albumin ratio was calculated for each patient.
resultsPatients who developed POAF were older; had higher rates of hypertension, carotid artery disease, left atrial diameter, urea, creatinine, uric acid, and C-reactive protein levels; and had lower hemoglobin and albumin levels. The uric acid-to-albumin ratio of patients with and without POAF was 1.65 ± 0.63 and 1.26 ± 0.39, respectively (P < 0.001). Compared with uric acid and albumin, uric acid-to-albumin ratio had the highest area under the curve for predicting POAF (0.681, 0.449, and 0.702, respectively). Age and hemoglobin concentration were predictors of POAF. Although uric acid and albumin did not reach statistical significance for predicting POAF, the uric acid-to-albumin ratio had predictive value for the development of POAF.
conclusionThe ability of the uric acid-to-albumin ratio to predict POAF in cardiac surgery patients and its nonnegligible benefits justify its use in clinical practice.
