1 · What the graph read from it

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.

2 · The registry

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

aimsThe purpose of this study was to assess the effectiveness of a smartphone app (MyHealthyGut) in helping adults self-manage celiac disease or gluten intolerance and improve their gut health.

methodsAdults diagnosed with celiac disease or gluten intolerance (

resultsParticipants reported high levels of app usability, were satisfied with features of the app, and felt that the app was best suited for people newly diagnosed with celiac disease. Participants in the experimental groups reported improvements in adherence, gastrointestinal symptoms (experimental group 1 only), QoL, self-regulatory efficacy (experimental group 2 only), anxiety (experimental group 1 only), and depression (experimental group 2 only). Experimental group 1 and the WLC group reported significantly worse adherence after using the app based on the Celiac Dietary Adherence Test, which was in contrast to the accidental and purposeful measures of gluten consumption and symptoms for experimental group 1 but consistent with reports of accidental and purposeful gluten consumption and symptoms for the WLC group.

conclusionsBased on feedback from the participants, the app may be best suited for individuals newly diagnosed or struggling with celiac disease or gluten intolerance. After using the MyHealthyGut app for a one-month period, adults with celiac disease reported improvements in psychosocial outcomes. Further iterations of the app are needed to meet the needs of this population better. MyHealthyGut is the first evidence-based app designed to help people with celiac disease or gluten intolerance.
