The Impact of a Digital Peer-Supported App on Daily Steps and Lifestyle Changes Among Individuals With Prediabetes and Early-Stage Type 2 Diabetes: Prospective, Nonrandomized Controlled Trial.
Article in JMIR formative research, 2025. 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
backgroundPhysical activity is a simple, low-risk intervention that could be integrated into daily life to improve glycemic control in individuals with prediabetes and early-stage type 2 diabetes mellitus (T2DM). However, maintaining physical activity remains challenging, even when its benefits are well understood. Although digital peer support has the potential to promote and maintain physical activity, its effectiveness has not yet been sufficiently established.
objectiveThis study examined the impact of a digital peer-supported app on daily step goal achievement and average daily step counts among individuals with prediabetes and early-stage T2DM.
methodsThis 3-month, prospective, nonrandomized controlled trial recruited participants aged 40-79 years with prediabetes or early-stage T2DM. The participants were divided into a digital peer-supported app group and a control group. The digital peer-supported app group tracked their daily steps, shared their progress with small peer groups, and received real-time feedback and support within the app. The control group tracked their steps individually using a pedometer. The primary outcome was the achievement rate of daily step goals. Secondary outcomes included the average daily step count, BMI, glycosylated hemoglobin A
resultsA total of 32 participants (digital peer-supported app group: n=18 and control group: n=14) completed the study. The digital peer-supported app group reported a significantly higher median daily step goal achievement rate (57.2%, IQR 32.2%-90% vs 26.7%, IQR 10%-64.4%; P=.04) and daily step count (6854, IQR 4846-10388 steps vs 3946, IQR 3176-6832 steps; P<.03) compared to the control group. No significant differences were observed in glycosylated hemoglobin A
conclusionsOur findings inform research in this field by suggesting that a digital peer-supported app may support daily step goal achievement and increase step counts among individuals with prediabetes and early-stage T2DM over the 3-month study period. The digital peer-supported app facilitated real-time feedback, peer approval, and continuous engagement to support participation in light physical activity.
