Analysis of risk factors for pulmonary infection in acute ischemic stroke patients following intravenous thrombolysis with alteplase.
Article in American journal of translational research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo identify the risk factors for pulmonary infection in acute ischemic stroke patients treated with intravenous thrombolysis using alteplase.
methodsA retrospective analysis was conducted on 110 acute ischemic stroke patients who received intravenous alteplase thrombolysis between January 2019 and November 2022. The patients were categorized into a pulmonary infection group (40 cases) and a non-infection group (70 cases).
resultsMultivariate logistic regression analysis identified the following independent risk factors for pulmonary infection: age, National Institutes of Health Stroke Scale (NIHSS) score at admission, underlying lung disease, hypertension, mechanical ventilation, aspiration, confusion, and elevated C-reactive protein (CRP) levels (all P<0.05). The sensitivity and specificity of CRP ifor predicting pulmonary infection were 88.57% and 75.00%, respectively. The NIHSS score demonstrated a sensitivity of 87.14% and a specificity of 70.00%. Further stratification of patients into a good prognosis group (75 cases) and a poor prognosis group (35 cases) revealed that high NIHSS scores at admission, increased fibrinogen (FIB) levels, a thrombolysis window exceeding 3 hours, and concurrent pulmonary infection were independent risk factors for poor prognosis. The area under the ROC curve for NIHSS in predicting prognosis was 0.890, and for FIB, it was 0.854 (P<0.001). The sensitivity and specificity of NIHSS for predicting poor prognosis were 89.33% and 82.86%, respectively, while for FIB, they were 84.00% and 82.86%.
conclusionsThese findings indicate that factors such as age, NIHSS score, underlying lung disease, hypertension, and elevated CRP levels significantly contribute to the risk of pulmonary infection in acute ischemic stroke patients. Clinicians should closely monitor these values to manage the risk of pulmonary infection effectively.
