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
introductionType 2 diabetes (T2D) and obesity are associated with substantial morbidity and healthcare spending. Although telehealth-delivered lifestyle interventions have demonstrated clinical benefits, evidence on their impact on healthcare costs and utilization remains limited. This study evaluated the association between participation in a comprehensive nutrition-first digital care model integrating individualized carbohydrate-reduced nutrition support, clinician-guided medication management, health coaching, and remote biometric monitoring on total healthcare costs and utilization over 1 year and 2 years.
methodsWe conducted a claims-based, retrospective propensity score matched difference-in-differences analysis of cost and utilization outcomes among US adults with T2D or obesity who (1) enrolled in Virta Health's Individualized Nutrition Therapy (INT) program or (2) had a primary care visit for either condition between 2017 and 2025. Per-member, per-month (PMPM) outcomes included inpatient, outpatient, and prescription medication costs, as well as inpatient, emergency department, primary care, cardiology, and endocrinology visits. For the T2D cohort only, PMPM costs for each diabetes medication were also evaluated.
resultsAmong 3819 adults with T2D and 2761 adults with obesity, program participation was associated with $240 and $256 PMPM reductions in total cost of care at 12 months, respectively (-$230 and -$189 PMPM over 24 months; all p < 0.001). Among adults with T2D, savings were driven by reduced inpatient visits and deprescription of sodium-glucose cotransporter 2 (SGLT2) inhibitors (66.8% reduction from baseline cost), sulfonylureas (51.7%), insulin (43.9%), and glucagon-like peptide-1s (GLP-1s) (32.2%). Among adults without T2D and with obesity, reductions accrued across all cost categories.
conclusionsIn this large, real-world analysis, enrollment in a comprehensive nutrition-first digital care model was associated with reductions in healthcare costs and utilization over 12 and 24 months, with prescription medication cost reductions emerging within the first quarter of treatment among adults with T2D. Together with prior evidence demonstrating clinical effectiveness, these findings suggest that comprehensive digital nutritional care models can generate meaningful economic value.
