Discharge NIHSS scores are predictive of poor 3-month outcomes in patients with acute Ischemic stroke receiving intravenous thrombolysis.

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 purposeWhile early National Institutes of Health Stroke Scale (NIHSS) scores are predictive of outcomes in patients with acute ischemic stroke (AIS), the prognostic value of the discharge NIHSS score after intravenous thrombolysis (IVT) remains unclear. We aimed to determine whether the discharge NIHSS score outperforms baseline, 24-hour, and early change indicators in predicting poor 3-month outcomes (modified Rankin scale [mRS] score of 3-6).
methodsIn this retrospective cohort study, we analyzed 554 AIS patients who received IVT at our stroke center from May 2022 to March 2024. NIHSS scores were assessed at baseline, 24 h, and discharge. Absolute (baseline minus discharge) and percentage (absolute change/baseline × 100%) NIHSS changes were calculated. Multivariable logistic regression analyses were used to assess the independent correlation between different NIHSS scores and poor outcomes. Predictive performance was evaluated using receiver operating characteristic (ROC) curves, net reclassification improvement (NRI), and integrated discrimination improvement (IDI).
resultsDischarge NIHSS scores demonstrated superior discriminative ability for poor outcomes (AUC 0.950, 95% CI 0.932-0.969) versus baseline (AUC 0.842), 24-hour (AUC 0.930), absolute change (AUC 0.689), and percentage change (AUC 0.885) (all
conclusionsThis study revealed a notable association between the discharge NIHSS score and poor 3-month outcomes in thrombolysis-eligible patients with AIS, particularly in those with moderate stroke severity. These findings complement the established prognostic value of the 24-hour NIHSS score and may guide postacute care planning.
