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
Aspiration pneumonia, a severe lung infection caused by inhaling endogenous flora or gastrointestinal contents, is a leading cause of mortality following a stroke. It often results from impaired swallowing, allowing substances to enter the lungs, especially in those with weakened cough reflexes. This compromises respiratory defenses, leading to pulmonary complications like aspiration pneumonia and acute respiratory distress syndrome, significantly increasing morbidity and mortality in stroke patients. Despite improvements in care, aspiration pneumonia remains a significant epidemiological and prognostic challenge for stroke patients, leading to heightened rates of mortality. To investigate the incidence, clinical outcomes, and predictors of mortality among stroke patients with aspiration pneumonia admitted to specialized hospitals in Western Amhara during the 2023/2024 armed conflict. A retrospective follow-up study was conducted with 191 patients from June 1, 2024, to August 30, 2024. Data were extracted from patient charts and entered into EpiData version 4.2, with statistical analysis performed using STATA version 17. Kaplan-Meier survival curves were employed to estimate survival probabilities, and the log-rank test was used to compare survival curves across different covariates. Adjusted hazard ratios with 95% confidence intervals were calculated to assess associations, with variables showing a p-value < 0.05 in multivariable analysis considered statistically significant. The study revealed a mortality rate of 23.56% among stroke patients who developed aspiration pneumonia, equivalent to 15.63 deaths per 100 person-Days, with a median survival time of 6 days. Patients with random blood sugar levels ≥ 200 mg/dL faced a 5.68-fold higher risk of mortality, while those who did not receive nasogastric tube therapy were 5.42 times more likely to die compared to those who did. This study highlights the significant burden of aspiration pneumonia in stroke patients. Key risk factors include elevated blood sugar levels and increased mortality risk, while nasogastric tube therapy offers protective benefits. Early interventions are crucial to reduce nasogastric tube impact and improve survival.
