Association between creatinine-to-albumin ratio and mortality in intracerebral hemorrhage: a superior predictive indicator.

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: Intracerebral hemorrhage is a severe and devastating condition with a high mortality rate worldwide. While creatinine and albumin levels have been studied individually, the prognostic value of the creatinine-to-albumin ratio in predicting mortality in intracerebral hemorrhage patients remains underexplored. Methods: We performed a retrospective cohort study of intracerebral hemorrhage patients from West China Hospital of Sichuan University (December 2010-July 2019) and The First People's Hospital of Longquanyi District, Chengdu (January 2017-October 2020). Serum biomarker data from blood samples were collected within 24 h of admission. The primary outcome is mortality, while secondary outcomes include renal, infectious, and neurological complications. Results: A total of 3,521 primary intracerebral hemorrhage patients were included in this study. Based on the Youden Index, 0.30 is the optimal threshold for dichotomizing creatinine-to-albumin ratio. Multivariate analysis showed that patients in higher quartiles of the creatinine-to-albumin ratio had significantly higher in-hospital mortality risks compared to those in the lowest quartile (Q1, reference group) (Q2: aOR 2.38, 95% CI: 1.40-4.03; Q3: aOR 2.87, 95% CI: 1.70-4.84; Q4: aOR 6.11, 95% CI: 3.68-10.15). Similar associations were observed for 30-day, 180-day, and 1-year mortality. Restricted cubic splines further supported this positive dose-response relationship. Receiver operating characteristic analysis showed that the creatinine-to-albumin ratio outperformed the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in prognostic performance, especially in predicting in-hospital mortality (AUC = 0.74). Additionally, the dynamic changes in creatinine-to-albumin ratio showed a significant increase in AUC over time ( Conclusion: Creatinine-to-albumin ratio can serve as an independent and superior predictor of mortality and complications in intracerebral hemorrhage patients. Its prognostic ability could surpass that of commonly used indicators, and its dynamic changes may provide additional valuable insights for prediction. However, further prospective studies are required to confirm its clinical applicability.
