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 and Aim: Handedness is a manifestation of cerebral lateralization that has been implicated in various neurological and neurodevelopmental conditions. Despite extensive research, the relationship between laterality and stroke outcomes remains underexplored. This study investigates the association between laterality (handedness, footedness, and ocular preference) and stroke severity. Methods: A cross-sectional study of 98 stroke patients from Tunisian hospitals assessed laterality (handedness, footedness, ocular preference) and NIHSS severity. Laterality was evaluated using validated questionnaires for manual, foot, and ocular preferences. Statistical analyses included nonparametric tests to examine the correlation between different aspects of laterality, the relationship between laterality (handedness, footedness, and ocular preference) and both stroke risk factors and stroke severity, as well as the correlation between stroke risk factors and severity, with a particular emphasis on the indirect impact of laterality. Results: The majority of participants were right-handed (66.3%), while 10.2% were left-handed and 38.8% demonstrated crossed laterality. No significant association was found between laterality and stroke severity ( Conclusion: The findings suggest that while laterality does not directly influence stroke severity, it may indirectly affect outcomes by modulating stroke risk factors. Therefore, laterality plays a crucial role in stroke, primarily through its impact on risk factors rather than directly determining severity.
