The effects of a mobile healthcare application on speech and swallowing in amyotrophic lateral sclerosis.
Article in Digital health. 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: Amyotrophic lateral sclerosis (ALS) impairs oral motor function, negatively affecting patients' speech and swallowing abilities, as well as quality of life. Objective: This study aims to evaluate the effectiveness of A Successful Swallowing with Effortful Training (ASSET) program, included in the 'The 365 Healthy Swallow Health Coach application' in preserving speech and swallowing abilities in ALS patients through self-training. Methods: In this 8-week quasi-experimental study, 13 participants were allocated to either the app-guided ASSET training group (n=7; three sessions per day, five days per week) or a usual-care control group (n=6) based on their clinical visit schedules. To evaluate changes over time and compare the two groups, linear mixed models were employed. Changes in ALS severity scale (ALSSS), Diadochokinetic (DDK) task, speech intensity, Speech Handicap Index-15, Dysphagia Handicap Index, Swallowing Quality of Life (SWAL-QOL), and Brief Inventory of Swallowing Assessment-15 were assessed. Results: ALSSS speech scores was relatively preserved from 5.43 (95% CI 3.01-7.84) to 5.29 (95% CI 2.87-7.70) in the ASSET treatment group, but declined from 6.33 (95% CI 3.73-8.94) to 4.83 (95% CI 2.23-7.44) in the control group, with a significant group-by-time interaction (p=.017). DDK/tuh/and/kuh/were relatively preserved from 11.86 to 11.71 and from 12.29 to 11.57 respectively in ASSET group, but declined from 11.67 to 7.50 and from 11.83 to 7.17 in the control group, with significant interactions in/tuh/(p=.032) and/kuh/(p=.044). SWAL-QOL total score was relatively preserved from 155.86 to 149.71 in ASSET group, but declined from 154.67 to 125.17 in the control group, with a significant interaction (p=.011). Conclusions: The findings suggest that ASSET program may help preserve speech and swallowing function in patients with ALS. Future research should validate the ASSET program with a larger, adequately powered sample size.
