Efficiency of Gla-300 versus Gla-100 Across Age Groups in People Living with Type 2 Diabetes in France: A Post Hoc Analysis of an Observational Longitudinal Study.
Observational study in Advances in therapy, 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
introductionThe EF-BI study, a nationwide observational and retrospective study conducted in France, found better insulin persistence, fewer insulin therapy-related acute hospitalizations, and lower healthcare costs in adults with Type 2 diabetes (T2D) who initiated treatment with insulin glargine 300 U/mL (Gla-300) compared to those who started on insulin glargine 100 U/mL (Gla-100) over a 3-year follow-up period. Given the heterogeneity of the T2D population, the benefits observed may vary according to individuals' characteristics. A post hoc analysis of this study was conducted to verify whether these findings were consistent in all age groups, including the elderly population.
methodsUsing the French national health insurance information system, adults with T2D who initiated basal insulin therapy with Gla-300 or Gla-100 between January 1, 2016, and December 31, 2020, and had no prior insulin use in the previous 6 months, were selected. Covariate adjustment using a propensity score based on key individuals' characteristics was applied to estimate outcomes and costs between the two basal insulins. Analyses were conducted using several age cut-offs (65, 75, and 80 years).
resultsOverall, 235,894 people with T2D were included: 175,537 initiated treatments with Gla-100 and 60,357 with Gla-300. Across both age groups (< 65 years or older), treatment with Gla-300 was associated with better persistence and a lower frequency of acute insulin-related events. Cost comparisons per individual treated over 3 years showed significant results favoring Gla-300:- €2,031 (- 7.3%, p < 0.0001) in the < 65 years group, and- €2,914 (- 7%, p < 0.0001) in the older group.
conclusionThis EF-BI post hoc analysis found that Gla-300 was associated with lower overall costs, better persistence, and fewer insulin-related acute events compared to Gla-100 in several age subgroups in people with T2D in France. Further investigations are needed to confirm these results, including glycemic control and comparison with other second-generation basal insulins.
