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 AND
aimsMalnutrition is common in older adults but poorly studied in acute ischaemic stroke (AIS) patients treated with endovascular thrombectomy (EVT). This study assesses the prevalence of malnutrition risk at Stroke Unit admission, related clinical factors, and its impact on EVT outcomes, functional status and 90-day mortality.
methodsRetrospective single-centre study on consecutive EVT-treated AIS patients (2021-2024). Malnutrition risk was assessed using the GNRI ([1.489 × serum albumin g/L] + [41.7 × current/ideal body weight]). For the primary analyses, patients with GNRI ≤ 98 were classified as at risk of malnutrition (RoM+); secondary analyses further stratified moderate-to-severe risk (GNRI < 92). Logistic regression was used to identify factors associated with RoM+ and to evaluate its impact on (1) EVT performance measures, (2) 90-day mRS and (3) 90-day mortality. Multivariable models included variables with p < 0.10 in univariate testing, and the robustness of outcome analyses was assessed through sensitivity models including predefined clinically relevant covariates.
resultsAmong 306 patients, 43.8% were classified as RoM+, including 24.5% with moderate-to-severe nutritional risk. In the multivariable model, RoM+ was independently associated with older age (aOR 1.03, 95% CI 1.00-1.06), higher pre-stroke disability (aOR 1.48, 95% CI 1.12-1.95) and a lower prevalence of dyslipidemia (aOR 0.59, 95% CI 0.35-0.97) and was not associated with EVT efficacy or safety. RoM+ was independently associated with increased 90-day mortality (aOR 2.37, 95% CI 1.06-5.28), while the association with functional outcome did not reach statistical significance (aOR 1.58, 95% CI 0.98-2.55). Secondary analyses using GNRI severity strata and predefined sensitivity models showed consistent results.
conclusionAt admission, ~44% of EVT-treated AIS patients are at risk of malnutrition, which independently predicted 90-day mortality. Pre-stroke nutritional status may represent a modifiable prognostic factor in stroke care and warrants further prospective investigation.
