The Effect of Prognostic Nutritional Index in Predicting Clinical Outcomes in Valve Replacement Patients.
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 3 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
introductionCardiopulmonary bypass is known to be a cause of systemic inflammatory response. The systemic inflammatory response affects albumin and lymphocyte levels and is associated with the development of complications. Serum albumin and lymphocyte concentrations have been used to create inflammation-based risk scores, which predict prognosis in different patient groups. One of these risk scores is called the Prognostic Nutritional Index (PNI). In this study, our objective was to examine how changes in PNI values, measured at different times before and after surgery, impact clinical outcomes and hospital mortality.
methodsOne hundred and sixty-four patients were retrospectively scanned and included in the study. Patients were divided into aortic valve replacement (AVR) and mitral valve replacement (MVR) groups. The patient's preoperative and postoperative PNI values were examined. Duration of cross-clamping, cardiopulmonary bypass time, length of hospital and intensive care unit stay, postoperative mortality, atrial fibrillation, and acute kidney injury (AKI) development were evaluated.
resultsPreoperative and second PNI values were lower in the patients that developed AKI and non-survivors. The PNI cutoff value was ≤ 28.01 in non-survivors (P=0.001). In the MVR group, the decrease in PNI value over time was statistically significant (P<0.001). There was a negative correlation between preoperative PNI value and length of stay in intensive care unit, cross-clamping, and cardiopulmonary bypass duration (P<0.05, P<0.01).
conclusionA correlation was determined between the PNI value and development of postoperative AKI and mortality. PNI value, an easy method to use, can be used in the follow-up of these patients.
