Aetiology of Acute Respiratory Insufficiency in Patients With Ischaemic Stroke Studied by Chest CT Scan.

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
backgroundAcute respiratory insufficiency (ARI) is considered a serious life-threatening complication after ischaemic stroke. The aim of this study was to identify the most common aetiologies of ARI after stroke and their association with patients' outcome.
methodsThis retrospective study was conducted at the University Hospital Bonn, involving patients with acute ischaemic stroke who underwent chest CT scans for ARI between 2017 and 2022. We collected clinical and demographic data, laboratory parameters, vital signs, as well as outcome parameters. CT scans were reviewed by a radiologist. The dataset was analysed to identify the most frequent aetiologies and their associations to outcome parameters.
resultsWe included 236 patients with a median age of 75 years and a median NIHSS score of 11. In-hospital mortality accounted for 30.5%. The most frequent pulmonary conditions on CT, in order of prevalence, included bronchitis/bronchiolitis (66.1%), atelectasis (66.1%), pleural effusion (60.6%), pneumonia (53%), pulmonary oedema (37.3%), and pulmonary artery embolism (27.5%). Bronchitis/bronchiolitis was an independent risk factor for mortality (OR = 3.17, 95% CI: 1.11-8.79, p = 0.03). A higher number of pulmonary conditions decreased the likelihood of discharge to home, and non-survivors had worse vital/laboratory parameters.
conclusionsWe identified six key pulmonary aetiologies of ARI after ischaemic stroke, with bronchitis/bronchiolitis notably linked to in-hospital mortality in our study cohort. An increased number of these acute pulmonary conditions decreased the likelihood of discharge to home. Early chest CT/CT-angiography may help to identify patients at high risk for in-hospital mortality and to initiate appropriate treatment early.
