Pharmacokinetic and Pharmacodynamic Drug-Drug Interactions Between Cofrogliptin and Metformin in Healthy Subjects: A Single-Center, Single-Arm, Phase I Study in China.
Article in Clinical pharmacology in drug development, 2026. 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
This single-center, single-arm, Phase I study evaluated drug-drug interactions (DDIs) between cofrogliptin and metformin in healthy Chinese subjects. Twenty-two subjects sequentially received metformin monotherapy (Days 1-4), cofrogliptin monotherapy (Days 6-34), and combination therapy (Days 38-47). Serial blood/urine samples were collected for pharmacokinetic (PK) and pharmacodynamic (PD) analyses. Cofrogliptin showed no significant impact on metformin's PK and PD properties: the geometric mean ratios (GMRs, metformin + cofrogliptin/metformin) with 90% confidence intervals (CIs) for metformin AUC
