Tongue Root Configuration of the Apicoalveolar Trill /r/: An Ultrasound Imaging Study.
Article in Communication disorders quarterly, 2023. 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
Common descriptions of articulatory requirements for production of the alveolar trill /r/ mainly focus on describing the configuration of the anterior portions of the tongue, while in contrast, the more posterior parts receive limited attention. Understanding how the posterior portions of the tongue move is vital for understanding speech motor control, especially with regard to speech development. This study used ultrasound imaging of /r/ productions by adult native speakers of Spanish to characterize the contribution of the posterior portion of the tongue to effective production of the sound. The results show that beyond raising the anterior portion of the tongue for trilling, Spanish speakers also retract the back part of their tongue (i.e., the tongue root). This movement resembles that seen for the production of the rhotic English approximant (ɹ). Clinical implications are discussed.
