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

purposeTo investigate the effect of repeated-sprint exercise in hypoxia on sleep quality.

methodsTen healthy young male adults performed three trials on different days: repeated-sprint exercise in normoxia (NOR, fraction of inspired oxygen [FiO

resultsTotal sleep time, sleep efficiency, sleep latency, duration of each sleep stage (non-REM [sleep stage without rapid eye movement] stages 1-3, REM) did not significantly differ among the three trials. During the first 90 min of sleep, HR was significantly higher in HYP (53 ± 2 bpm) than in REST (49 ± 1 bpm, P < 0.05). Furthermore, pNN50 was significantly lower in both HYP (48.8 ± 4.8%) and NOR (50.4 ± 4.9%) than in REST (58.3 ± 3.6%, P < 0.05).

conclusionPerforming repeated-sprint exercise in hypoxia in the early evening altered HRV-derived indices during the first 90 min of sleep, without markedly affecting sleep quality.
