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

This study examined how the time of day influences cognitive coordination in elite male handball players. We investigated misunderstandings and contradictions during cognitive exchanges to identify optimal times for shared understanding and collective performance. Six elite male handball players (age 17.5 ± 0.2 years) from Tunisia's first division participated in simulated matches at three different time points: (10h00, 14h00, and 18h00). We analyzed cognitive coordination using audiovisual recordings and self-confrontation interviews, applying the Recognition-Primed Decision (RPD) model. Results revealed significantly higher frequencies of contradictory and misunderstanding coordination forms during morning sessions compared to afternoon and evening sessions across all cognitive components (actions, relevant cues, goals, expectations). These findings suggest that circadian factors influence team cognitive coordination, with the afternoon and evening periods being optimal for collective performance, which requires sophisticated coordination and a shared understanding.
