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

The cortisol awakening response (CAR) shows promise as a tool for tracking stress, recovery, and fatigue, although questions around CAR stability in elite sport exist. A functional cortisol link to testosterone and its awakening response (TAR) could also affect the CAR and endpoint outcomes, with stress as a moderating factor. To help resolve these issues, we investigated the day-to-day dynamics of the CAR and TAR in elite athletes and controls. Saliva samples (i.e., waking, waking+30 minutes) were taken from 29 male rugby players (mean age 26.4 years) on four consecutive days and 42 male controls (age 31.0 years) on two consecutive or non-consecutive days.
