Behavioral and human-computer interaction requirements for a candidate abdominal-sound-enabled dietary self-regulation system: a two-phase study in Taiwanese university students.
Article in Frontiers in nutrition, 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
Background: Wearable nutrition tools frequently prioritize calorie surveillance and retrospective logging. However, university students may require low-friction support that aligns with everyday eating contexts. The hypothesis that abdominal sounds could serve as biologically plausible future gastrointestinal timing cues is well-founded. The purpose of this study was to define the behavioral and human-computer interaction (HCI) requirements for a candidate abdominal-sound-enabled dietary self-regulation system among Taiwanese university students. Methods: The manuscript integrates two empirically linked phases. Phase 1 was a formative cross-sectional study of Taiwanese university students ( Results: The Positive Eating Scale exhibited a two-factor structure (KMO = 0.85; Bartlett's chi-square (28) = 14,605.46, Conclusions: The extant evidence supports the implementation of a non-punitive, satisfaction-centered, adaptive, and low-friction interface architecture for future wearable dietary self-regulation. Abdominal sounds should be interpreted solely as a candidate timing/context input until participant-level acoustic validation and downstream gut-brain-axis endpoints are obtained.
