Addition of continuous glucose monitoring to glucagon-like peptide 1 receptor agonist treatment for type 2 diabetes mellitus - An economic evaluation.
Article in Journal of managed care & specialty pharmacy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundBoth glucagon-like peptide 1 receptor agonists (GLP-1 RAs) and continuous glucose monitoring (CGM) have been shown to improve glycated hemoglobin A1c (A1c) levels among patients with type 2 diabetes mellitus (T2DM). Recently, a US real-world study found statistically significant improvements in A1c levels among patients using GLP-1 RA and a CGM device, compared with a matched cohort receiving only GLP-1 RA.
objectivesTo assess the cost-effectiveness from a US payer perspective of initiating CGM (FreeStyle Libre Systems) in people living with T2DM using a GLP-1 RA therapy, compared with GLP-1 RA alone.
methodsA patient-level microsimulation model was run for 10,000 patients over a lifetime horizon with 3.0% discounting for costs and utilities. Patient characteristics were based on the overall population of the US real-world study and the subgroup of patients not using intensive insulin. The effect of CGM was modeled as a persistent reduction in A1c compared with GLP-1 RA alone (overall = 0.37%; patients not using intensive insulin = 0.34%). Costs ($2,023) and disutilities were applied to diabetes complications and acute diabetic events. Outcomes were assessed as quality-adjusted life years (QALYs).
resultsThe base-case incremental cost-effectiveness ratio (incremental costs/incremental QALYs) for GLP-1 RA plus CGM vs GLP-1 RA alone was $40,968/QALY in the overall cohort (cost = $484,180 vs $473,938; QALYs = 13.37 vs 13.12). Among patients not using intensive insulin, the incremental cost-effectiveness ratio was $43,095/QALY. Scenario analysis showed that the model results were robust to changing assumptions. Probabilistic sensitivity analysis showed that GLP-1 RA plus CGM had a 64% probability of being cost-effective at a willingness-to-pay threshold of $100,000 per QALY.
conclusionsFrom a US payer perspective, CGM is cost-effective when added to GLP-1 RA therapies for the treatment of T2DM, including for patients not using intensive insulin.
