Transcriptomic and Machine Learning-Based Classification of Unprovoked Versus Provoked Venous Thromboembolism Using Public Data.
Article in IET systems biology. 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
Venous thromboembolism (VTE) comprises provoked and unprovoked forms; accurate classification informs anticoagulation duration and recurrence risk but is limited by clinical phenotyping. We analysed the GSE48000 whole-blood transcriptomes to identify differentially expressed genes (DEGs) between provoked and unprovoked VTE. DEGs underwent GO and KEGG enrichment. Random forest ranked features, and an artificial neural network (ANN) built on the top 30 genes was trained and evaluated discrimination using stratified 10-fold cross-validation with receiver operating characteristic (ROC) analysis. A 30-gene signature cleanly separated the two subtypes. Most genes showed lower expression in unprovoked VTE, with a notable upregulation of GDF2, LGALS2, and LOC100130229. Enrichment analyses highlighted immune regulation and vesicle-transport pathways. The ANN achieved an AUC of 0.799 in this dataset. Transcriptomic profiling coupled with machine learning distinguished provoked from unprovoked VTE with excellent discrimination, supporting the feasibility of artificial intelligence (AI)-based molecular diagnostics for classification and risk assessment. Prospective validation in larger, independent cohorts is warranted.
