Guanine and pregnenolone sulfate are associated with incident type 2 diabetes in two independent populations.

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
Background: Type 2 diabetes (T2D) is increasing its burden worldwide; therefore, research focused on its prediction and prevention is essential. Methods: We performed an untargeted metabolomics analysis using ultra high-performance liquid chromatography-mass spectrometry to discover metabolic biomarkers and biological pathways associated with incident T2D with a nested case-control design, followed by validation with targeted metabolomics in an independent cohort. In the discovery phase, plasma samples from 352 subjects (209 controls and 143 incident cases) were analyzed, collected with a mean (standard deviation) of 7.40 (0.76) years before they acquired the condition. Using this discovery phase cohort, six metabolites were identified using standards and were subsequently quantified in an independent validation phase cohort of 2,044 subjects (167 incident cases). Additionally, pathway enrichment was conducted in the discovery cohort. Results: Guanine, ecgonine, adenine, pregnenolone sulfate, phenyl sulfate, and citrulline were significantly associated with incident T2D in at least one of the analyses performed in the discovery phase. Among these, guanine, pregnenolone sulfate, and citrulline maintained their significant associations with incident T2D in the validation cohort. Additionally, several pathways were significantly altered, with nucleotide metabolism and ABC transporter pathways among the most consistently affected. Conclusion: We identified significant associations of guanine, pregnenolone sulfate, and citrulline with incident T2D.
