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/

objectiveAppropriate hydration is essential for track-and-field sprinters to optimize training and competition performance. A recently developed estimation equation evaluates water turnover (WT) based on body size, environmental, and lifestyle factors. However, the assumption in the estimation equation-which may imply that athletes feel thirstier and have greater voluntary water intake than non-athletes because of an attenuated thirst-suppressing response-may not be applicable to sprinters engaged in high-intensity training. This study aimed to validate the estimation equation for WT in sprinters. MATERIALS/

methodsTwenty-four male collegiate sprinters participated in this study. The WT in participants was estimated and measured using the estimation equation (WT

resultsWT

conclusionOur findings indicate that the estimation equation overestimated WT by approximately 500 mL/day in male collegiate sprinters. These results suggest that sprinters should carefully consider the discrepancy difference between estimated WT and WT measurand using DLW method when using the estimation equation for hydration management.
