Tongue pressure and self-assessment of swallowing after total laryngectomy.
Article in CoDAS, 2025. 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
purposeTo evaluate tongue pressure, self-perception of swallowing, and whether tongue pressure is correlated with self-perception of swallowing in individuals undergoing total laryngectomy.
methodsCross-sectional study with two groups - with and without total laryngectomy, matched by age and sex to individuals with total laryngectomy. Participants had their tongue tip and dorsum pressure measured and self-assessed their swallowing with the Swallow Outcomes After Laryngectomy questionnaire (SOAL).
resultsThe sample totaled 26 participants, 13 from each group. The mean maximum tongue dorsum pressure was 41.2±18.7 and 27.9±9.3 kilopascals, respectively, in the groups with and without total laryngectomy (p = 0.03). The median maximum tongue tip pressure was 33.7 (23.8-49.3) and 29.1 (22.5-35.7) kilopascals, respectively, in the groups with and without total laryngectomy (p = 0.29). The median SOAL was 6 (2.5-8.5) points in the group with total laryngectomy. The SOAL score was not statistically significantly correlated with tongue tip pressure (r = -0.17; p = 0.58) or dorsum pressure (r = -0.30; p = 0.31).
conclusionIndividuals with total laryngectomy had higher tongue dorsum pressure, although there was no difference in tongue tip pressure between individuals with and without total laryngectomy. Tongue pressure was not correlated with self-assessment of swallowing, although tongue tip pressure was correlated with dorsum pressure in individuals with total laryngectomy.
