Monocyte-lymphocyte ratio as a predictor of 3-month mortality in elderly heart failure patients: a retrospective Chinese cohort study.

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: Heart failure (HF) represents the terminal phase of cardiovascular disease and is the primary cause of mortality in elderly patients diagnosed with HF. Precise early prediction of HF onset and progression is crucial for enhancing survival rates in patients. Central to HF's pathophysiology is inflammation, with the monocyte-lymphocyte ratio (MLR) emerging as a potential novel inflammatory marker. The relationship between MLR and HF in the elderly is not well-defined. Therefore, this study, utilizing the 2016-2019 Sichuan Zigong Heart Failure Database, aimed to explore the correlation between MLR levels and 3-month mortality in elderly HF patients within the Chinese population. Methods: A retrospective cohort study was conducted using the 2016-2019 Heart Failure Database from Zigong City, Sichuan Province, China. HF was identified based on the diagnostic criteria of the European Society of Cardiology. The MLR was calculated as monocyte count divided by lymphocyte count. Both lymphocyte and monocyte counts were sourced directly from laboratory datasets. Cox regression analysis was performed to assess the relationship between MLR and 3-month mortality, with stratified evaluations conducted based on age, gender, and comorbidity index. Results: Of the 1,448 elderly HF patients assessed, multivariate regression analyses revealed that the high-level MLR group had a heightened occurrence of 3-month mortalities, presenting a hazard ratio (HR) and a 95% CI of 3.31 (1.42-7.7). In the subgroup analyses, the effect sizes of MLR remained consistent across all subgroups (all Conclusion: MLR is significantly associated with 3-month mortality rates in elderly HF patients. Early MLR evaluations might offer a pathway to augment the life quality and survival outcomes of these patients.
