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

Objectives: Psychometric Validation of the Study design: Cross-sectional. Methods: The study was conducted in a school setting in the western region of central Portugal between April 10 and 12, 2024, using a convenience sample of children aged 10-12 years. The Results: The initial scale showed good internal consistency (Cronbach's α = 0.875). Four items were removed due to low item-total correlations and factor loadings. The revised 38-item version demonstrated improved reliability (Cronbach's α = 0.889), acceptable inter-item correlations, and good model fit (χ Conclusions: The
