MRA and Doppler ultrasound of laryngeal blood flow under hormonal and hydration modulation.
Article in BMC research notes, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
objectivePhonation is a complex process requiring an appropriate tissue environment of the vocal folds, with laryngeal blood flow serving as one factor that contributes to tissue homeostasis. Effects of dehydration and reproductive hormone cycling to blood flow and vascular dynamics are described in the literature, but there is a gap in our understanding how these factors may influence the laryngeal blood supply directly. The present study has used a mild systemic dehydration and hormone manipulation paradigm in rats to evaluate the related impacts to the superior thyroid artery using Doppler ultrasound and time-of-flight magnetic resonance angiography.
resultsThis study provides evidence that hormone status can modify the manifestation of mild systemic dehydration as reflected in bodyweight loss. The imaging methods employed did not reliably identify perturbations to blood flow related to either hydration or hormone status, which we attribute to their practical resolution with respect to the superior thyroid artery and subtlety of the hypothesized effects.
