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

BACKGROUND/

objectivesDiet quality is relevant to athlete health and recovery, yet practical methods for assessing dietary patterns in elite sporting environments remain limited. This exploratory study aimed to examine the relationship between skin carotenoid status and diet quality in male professional National Rugby League players.

methodsSkin carotenoids were assessed at three time points throughout the NRL season: pre-, mid-, and end-season. The Veggie Meter

resultsCorrelations between carotenoid status and diet quality score varied across time points: pre-season, r = 0.297, 95% CI -0.094 to 0.608,

conclusionsThis exploratory study provides preliminary evidence that skin carotenoid status may reflect aspects of diet quality in elite NRL players, although associations varied across time points and only reached statistical significance at mid-season. Non-invasive tools such as the Veggie Meter
