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

Saliva, specifically salivary osmolality, has gained increasing interest as a non-invasive hydration marker providing rapid results that can be easily obtained in a field setting. However, it is unclear as to whether commercially available hydration devices can accurately measure salivary osmolality. Thus, this study assessed the validity of the MX3 Portable Hydration device against a laboratory-grade freezing-point depression benchtop osmometer (i.e., criterion measure). A total of eight saliva samples were collected from 10 male participants (total saliva samples,
