From Bench to Bedside: Evaluating a Low-Cost Tongue Pressure Device Prototype for Clinical and Community Use.
Article in Journal of International Society of Preventive & Community Dentistry. 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
Aim: This study evaluated the test-retest reliability, concurrent validity, and usability of the Chulalongkorn University Prototype Tongue Pressure Instrument (CUPTI), a novel low-cost manometer for maximum tongue strength (MTS) measurement, in comparison to the standard Iowa Oral Performance Instrument (IOPI). Materials and Methods: Sixty healthy adults (20-80 years) were randomized into two groups in a cross-over design. Participants underwent MTS assessment using both devices. Reliability was assessed through intraclass correlation coefficients, while concurrent validity was evaluated through Pearson correlation and Bland-Altman analysis. Effect size (Cohen's Results: Both CUPTI and IOPI demonstrated excellent test-retest reliability (ICC > 0.95). CUPTI consistently recorded lower MTS values, with a mean bias of -8.12 kPa (limit of agreement: -2.52 to 18.76 kPa). A strong correlation ( Conclusion: CUPTI is a valid and reliable alternative to IOPI, offering affordability and accessibility for clinical and community dysphagia screening. Its performance supports implementation in resource-constrained settings and home-based rehabilitation.
