Effects of Using a Digital Peer-Supported App on Glycated Hemoglobin Changes Among Patients With Type 2 Diabetes: Prospective Single-Arm Pilot Study.
Article in JMIR formative research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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: Controlling glycated hemoglobin (HbA1c) levels can be challenging for patients with type 2 diabetes mellitus (T2DM). Peer support promotes HbA1c control, and a digital peer-supported app designed for group interactions may enable patients with T2DM to encourage one another to achieve better HbA1c outcomes. However, no studies have investigated the use of digital peer-supported apps to control HbA1c levels in patients with T2DM. Objective: This pilot study aimed to explore the effects of a digital peer-supported app on HbA1c control in patients with T2DM. Methods: This prospective single-arm pilot study enrolled patients with T2DM who owned smartphones and visited medical institutions in Japan. During the 3-month intervention, participants used a digital peer-supported app in addition to receiving standard care. This app allowed participants to share activity logs and concerns via a chat function to improve HbA1c levels through mutual engagement and encouragement. The primary outcome was the change in HbA1c levels, measured at health care facilities at baseline and after 3 months. The secondary outcomes were body weight and blood pressure, with the most recent data obtained from hospitals and clinics. Physical activity (≥1 hour/day) was assessed at the same time points using a self-reported questionnaire. Results: The study included 21 participants with a median age of 56 (IQR 51-61) years, of which 13 (61.9%) were female. After using the digital peer-supported app for 3 months, the participants' HbA1c levels significantly decreased from 7.1% (SD 0.6%) at baseline to 6.9% (SD 0.1%) (P=.04). Similarly, participants' body weight decreased from 70.7 (SD 12.7) kg to 69.9 (SD 12.4) kg (P =.004) through app use. Although blood pressure decreased slightly from 128.2 (SD 12.5) mm Hg to 126.0 (SD 12.9) mm Hg, this change was not statistically significant (P=.20). Additionally, the proportion of participants engaged in ≥1 hour of daily physical activity significantly increased from 23.5% (n=4) to 58.5% (n=10) (P=.03). Conclusions: In addition to receiving standard clinical care, the use of a digital peer-supported app may significantly lower HbA1c levels in patients with T2DM by promoting healthy behaviors.
