Acute Effects of Sleep Extension on Fatigue, Inhibitory Control, Short-Term Vigilance and Neuromuscular Function in Youth Elite Ice Hockey Players: A Randomised Crossover Trial.
Trial report in Journal of sleep research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Sleep extension has previously been shown to acutely benefit athletic performance. However, studies investigating the effects of sleep extension on fatigue and cognitive performance are lacking. In this randomised crossover trial, 22 elite youth hockey players (17 ± 1 years; 1.83 ± 0.07 m; 82 ± 7 kg) took part in a 3-week protocol during the pre-season. The first week included two familiarisation sessions. During the second and third week of the protocol, athletes underwent a testing session before and after a night of normal sleep vs. sleep extension (10 h of time in bed). For each athlete, these conditions were randomised across weeks. Each testing session consisted of 2 h of hockey training followed by a 30-min colour Multi-Source Interference Task (cMSIT). Three countermovement-jumps (CMJs), three handgrip contractions and 3-min psychomotor-vigilance tasks (PVTs) were performed pre-training, post-training, and post-cMSIT. Sleep was objectively monitored using actigraphy and sleep logs. Athletes slept normally 7:04 ± 0:39 h:mm. In the sleep extension condition, athletes increased their sleep by 16% ± 11% (p < 0.001; η
