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
Introduction: Diabetes is a chronic metabolic disorder characterized by elevated blood glucose (BG) levels, with poor control linked to serious long-term complications. Managing BG effectively requires personalized strategies, given the influence of demographic, lifestyle, and clinical factors. Machine learning (ML) offers a powerful framework for analyzing complex, real-world data to uncover individual patterns of glycemic control. Coupled with digital health platforms that enable real-time monitoring and behavioral engagement, these tools can transform diabetes care. This study leverages data from the Dario digital health platform to examine BG trends moderated by clinical and engagement variables, aiming to inform personalized digital interventions. Objective: To apply ML techniques to digital health data to identify moderating factors that influence individual BG trajectories, supporting data-driven and personalized diabetes management. Methods: A retrospective cohort study was conducted using real-world data from users with type 2 diabetes and baseline BG ≥180 mg/dL who measured BG over at least two separate months between 2020 and 2024. A piecewise linear mixed-effects model characterized BG changes over time. Generalized Linear Mixed Effects Tree models identified subgroups with distinct BG trajectories based on demographic (age, gender, BMI, ethnicity), clinical (insulin use, comorbidities, diagnosis year), and monitoring factors. An additional model tested whether lifestyle engagement (e.g., meal and activity logging) moderated BG improvement across age groups. Results: Data from 22,414 users (49.9% male; mean age 57.5; BMI 34.5) showed significant reductions in monthly average BG over 12 months (B = -6.8 in months 1-4; B = -0.3 in months 4-12; both Conclusion: Machine learning can reveal distinct glycemic trajectories moderated by demographic, clinical, and engagement factors. These findings underscore the potential of digital health platforms to personalize diabetes care and improve blood glucose management through adaptive, data-driven strategies.
