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
BackgroundPrehospital stroke screening for large vessel occlusions (LVOs) varies across institutions. This study compares manual stroke scale calculations against e-calculated scores using the Ultimate Stroke Scale (USS), a software automating multiple screening scales from a modified National Institutes of Health Stroke Scale (NIHSS) with a hand grip. The USS aims to streamline screening by computing multiple validated stroke scales simultaneously to enhance predictive value.MethodsWe applied eight stroke screening scales (NIHSS; Balance, Eyes, Face, Arms, Speech, and Time [BE-FAST]; Vision, Aphasia, Neglect; Los Angeles Motor Scale [LAMS]; Face, Arm, Speech, Time, Eye Deviation and Denial/Neglect [FAST-ED]; Emergency Medical Services Rapid Arterial oCclusion Evaluation [EMS RACE]; 3-Item Stroke Scale [3-ISS]; and Prehospital Acute Stroke Severity [PASS]) to 199 stroke activations between January 2021 and December 2023. In this prospective, external validation study, data were utilized from a previously published head-to-head comparison of multiple LVO scales for both LVOs and medium vessel occlusions which collected scales manually. We recalculated these scales using the USS and evaluated agreement (Kendall's τ) and diagnostic accuracy (ROC curves).ResultsThe USS showed strong to moderate agreement with manual calculations across all scales displayed by Kendall's τ correlation coefficients ranging from 0.549 to 0.931 (all
