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 explores the dynamics of sleep, somatic/psychological experience, and exercise performance before, during, and after the Tour de France (TDF). Objective and subjective sleep, self-reported perceived experience, and objective exercise performance data were collected daily from eight elite male cyclists across a 6-week period including the 3-week TDF and 11-day pre- and post-race periods. Associations between, and temporal changes in, primary interest metrics were explored through Pearson correlation and linear mixed models. Participants were (mean ± SD) aged 30 ± 4 years with overall objective sleep duration of 8 h 11mins (±58 min) per night. Sleep quality (0-100) was lower during the race than pre-race (β [95% CI]; -8.0[-11.7, -4.3]). During the pre-race period, sleep onset (4 [2, 5] mins) and offset times delayed (5 [3, 7] mins) and self-reported stress increased (1.87 [1.14, 2.61]) daily. Increases in muscular soreness (0.6 [0.3, 0.8]) and fatigue (0.4 [0.2, 0.6]) during the race preceded daily declines during the post-race period (-3.1 [-4.0, -2.1]; -2.7 [-3.5, -1.8]). Relative performance output (Performance Index; 0-1000) negatively predicted sleep duration (r [95% CI]; -0.32 [-0.46, -0.17]) and sleep quality (-0.34 [-0.47, -0.19]) during the race. Temporal changes in, and associations between, sleep timing, perceived experience, and exercise function highlight the potential for sleep-improvement strategies that enhance performance in naturalistic endurance sporting contexts.
