Threshold Effect of the Lymphocyte to HDL-C Ratio on the Risk of Stroke-Associated Pneumonia After Acute Ischemic Stroke: A Retrospective 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: Stroke-associated pneumonia (SAP) is a severe complication of acute ischemic stroke (AIS). While post-stroke immunosuppression and metabolic dysregulation are implicated in its pathogenesis, biomarkers integrating these pathways are needed for early risk stratification. We evaluated the lymphocyte-to-HDL-cholesterol ratio (LHR), a marker of immune-metabolic status, as a predictor for SAP. Methods: We retrospectively analyzed 978 consecutive AIS patients from a single-center cohort. The primary outcome, SAP, was diagnosed based on modified Centers for Disease Control and Prevention criteria within the first 7 days of hospitalization. The relationship between the LHR, calculated from baseline measurements on admission, and SAP was assessed using smooth curve fitting and multivariable logistic regression, adjusting for potential confounders (eg, age, sex, key comorbidities, and thrombolysis treatment). The association's robustness was tested via subgroup and sensitivity analyses. Results: SAP occurred in 9.2% (90/978) of patients. A distinct nonlinear, L-shaped association was found: SAP risk increased sharply as LHR fell below an empirically identified threshold of approximately 1.0, while remaining consistently low at higher LHR values. In the fully adjusted model, a low LHR (<1.0) was independently associated with a nearly twofold increased risk of SAP (adjusted OR 1.98; 95% CI, 1.20-3.24; Conclusion: A low admission LHR (<1.0) serves as a novel, independent predictor of SAP in AIS patients, exhibiting a clinically relevant data-driven threshold effect. As a cost-effective and readily available biomarker reflecting the interplay between immunity and metabolism, LHR holds significant potential for early risk stratification using this empirically derived cut-off, particularly in resource-limited settings.
