1 · What the graph read from it

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.

2 · The registry

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: Advances in stroke care have led to an increase in the number of patients who regain independent indoor ambulation; however, many still experience limitations when attempting to resume community activities. Altered prefrontal cortex (PFC) activity during dual-task walking (DTW) after stroke has been suggested as a contributing factor to difficulties with community ambulation. The purpose of this study was to compare PFC oxygenation dynamics and walking performance during DTW between independently ambulatory patients with acute stroke and healthy older adults. Methods: A total of 36 independently ambulatory patients with stroke within 14 days of onset (74.8 ± 6.3 years; 44% female) and 17 healthy older adults (71.4 ± 4.1 years; 41% female) were included in this cross-sectional observational study. Each participant performed normal walking as a single task (Walk-ST), serial subtraction as a single task (Serial-7-ST), and DTW tasks. We measured PFC oxygenation by assessing oxyhemoglobin (O Results: Significant task effects were observed for both O Conclusion: Ambulatory patients with acute stroke exhibited poorer walking performance than did healthy older adults, despite showing no significant between-group differences in task-related PFC oxygenation dynamics or cognitive performance.
