Canagliflozin protects cardiovascular function in type 2 diabetic coronary artery disease by regulating natriuretic peptide B.
Article in Journal of diabetes investigation, 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
backgroundCanagliflozin (Cana) has protected against diabetes-related cardiovascular disease. This study was intended to explore the effect and molecular mechanism of Cana on cardiovascular protection in type 2 diabetic coronary atherosclerotic heart disease (CAD). MATERIALS AND
methodsWe constructed a rat model of type 2 diabetic CAD and examined its physiological and biochemical indices before and after Cana treatment. Next-generation transcriptome sequencing was performed on rat cardiac tissue. Various functional and molecular experiments involving Cana treatment and the natriuretic peptide B (NPPB) gene were performed on human cardiomyocytes (AC16 cells).
resultsThe physiological, biochemical, and imaging parameters of the model rats were abnormal. Cana treatment reversed these injuries. In all, 369 differentially expressed genes were discovered by next-generation transcriptome sequencing; NPPB was identified as the target gene. Cana treatment significantly improved the function of AC16 cells treated with high glucose and significantly upregulated the expression level of the NPPB gene. The NPPB gene significantly increased the viability of AC16 cells and significantly decreased the apoptosis rate and reactive oxygen species (ROS) level. In addition, NPPB significantly upregulated the expression of B-cell lymphoma 2 (Bcl-2) and downregulated the expression of Bcl-2 associated X protein (Bax). Cana treatment further improved these cellular functions and protein expression levels. Furthermore, the NPPB gene significantly upregulated protein kinase 1-α (PKG1α) expression level and Cana treatment enhanced the regulatory effect of NPPB on PKG1α.
conclusionsThe cardiovascular protective effect of Cana in diabetes mellitus was mediated by upregulating the expression of NPPB and upregulating the level of PKG1α, which in turn regulated the viability, apoptosis rate, and ROS level of AC16 cells.
