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: Pneumonia is a common and serious complication among patients with intracerebral hemorrhage (ICH), contributing to increased morbidity and mortality. Early identification of patients at high risk for pneumonia is essential for implementing preventive strategies and improving outcomes. The neutrophil-to-high-density lipoprotein cholesterol ratio (NHR) has emerged as a novel marker of systemic inflammation with potential predictive value. This study examines whether elevated NHR is associated with an increased risk of pneumonia in patients with ICH, aiming to evaluate NHR as a practical biomarker for early risk prediction. Methods: This retrospective multicenter cohort study included patients diagnosed with intracerebral hemorrhage (ICH) from three hospitals: West China Hospital of Sichuan University (December 2010 to August 2019), The First People's Hospital of Longquanyi District, Chengdu (December 2016 to November 2020), and the Affiliated Hospital of Chengdu University (August 2012 to November 2020). Patients were stratified into two groups based on their NHR: less than 6.84 and 6.84 or greater. The primary outcome was the occurrence of pneumonia during hospitalization. Results: Among the 2,639 patients, the incidence of pneumonia was 27.5% (363 of 1,320) in the low NHR group (NHR < 6.84) and 47.4% (625 of 1,319) in the high NHR group (NHR ≥ 6.84). Unadjusted models showed that patients in the high NHR group had a significantly increased risk of developing pneumonia compared to those in the low NHR group (odds ratio [OR], 2.37; 95% confidence interval [CI], 2.02-2.79; Conclusion: Elevated NHR was significantly associated with an increased risk of pneumonia among patients with intracerebral hemorrhage. Given its simplicity and potential diagnostic value, NHR may serve as a useful biomarker for predicting pneumonia risk in this population, facilitating early identification and potentially improving patient outcomes.
