Association of Preoperative Leukocyte-to-Albumin Ratio with Short- and Long-Term Outcomes After Valvular Heart Surgery: A Retrospective Cohort Study.
Article in Journal of inflammation research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: The leukocyte-to-albumin ratio (LAR) serves as an integrated marker of both inflammation and nutritional status. However, there is currently a lack of research on the correlation between LAR and the prognosis of valvular heart disease (VHD) surgery patients. This study investigates the prognostic significance of LAR in patients undergoing VHD surgery. Methods: This is a single-center, retrospective cohort study. From May 2021 to July 2024, we retrospectively analyzed the clinical data of 773 patients who underwent VHD surgery. Patients were categorized into low- and high-LAR groups using a threshold value of 0.2. Multivariable logistic regression models were used to assess the association between the LAR and adverse outcomes. Results: This study included a total of 773 patients, with 615 in the low LAR group and 158 in the high LAR group. The main findings included that LAR ≥ 0.2 was an independent protective factor for severe arrhythmias(SA)(OR:0.231, 95% CI:0.103-0.518, Conclusion: In summary, an elevated LAR (≥0.2) exhibits a paradoxical role, serving as an independent predictor for reduced SA while concurrently correlating with an extended LOS, thereby establishing its dual nature as a perioperative risk biomarker.
