Strengthening inferential studies in the FDA Sentinel initiative: results from a methodological demonstration project.
Article in NPJ digital medicine, 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
The FDA Sentinel Real-World Evidence Data Enterprise (RWE-DE) contains linked electronic health records with claims data for over 25 million patients. To demonstrate the applicability of the RWE-DE to a study previously considered infeasible in claims-based Sentinel network, we emulated a target trial using a case study comparing acute pancreatitis among new users of sodium-glucose cotransporter-2 inhibitors (SGLT-2i) with new users of dipeptidyl peptidase-4 inhibitors (DPP-4i) among 97,119 patients with type 2 diabetes mellitus from HealthVerity [2018-2020] and TriNetX [2013-2024] databases. We applied a previously validated computable phenotyping algorithm using EHRs to identify acute pancreatitis as the primary outcome. After confounding adjustment for >135 variables using propensity score fine stratification weighting, the hazard ratio (95% confidence interval) for acute pancreatitis following SGLT-2i initiation compared to DPP-4i initiation was 0.85 (0.67-1.07) for intent-to-treat and 0.84 (0.58-1.22) for per-protocol analysis. This study serves as a proof-of-concept for future safety assessments in Sentinel.
