MultiOmicsXplorer, a tool to browse, access and analyse multi-omics data.
Article in BMC bioinformatics, 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
backgroundPersonalized and precision medicine aim to identify predictive biomarkers from patient-specific proteogenomic profiles and to uncover tailored therapeutic strategies by targeting deregulated proteins driving disease phenotypes.
methodsTo address these challenges, we developed MultiOmicsXplorer, a freely available and interactive R-based Shiny application designed to facilitate the exploration and analysis of multi-omics cancer datasets with a user-friendly interface. At its core, MultiOmicsXplorer builds on our recently developed SignalingProfiler pipeline to extract protein activities from proteogenomic data, thereby reducing data complexity and dimensionality while enabling mechanistic hypothesis generation.
resultsThe application integrates two core functionalities. The first, OncoXplorer, enables the systematic inference and comparison of protein activities from 1492 samples corresponding to approximately 1000 patients across ten cancer types, leveraging harmonized datasets from the CPTAC portal to provide a functional and mechanistic interpretation of multi-layered data. Importantly, beyond activity estimation, it allows for comparative analysis of transcriptomic, proteomic, and phosphoproteomic data. The second module, Extract Protein Activity from Your Data, enables users to infer the activity of kinases, phosphatases, and transcription factors from custom multi-modal datasets.
conclusionsOverall, MultiOmicsXplorer facilitates the exploration and interpretation of CPTAC multi-omics cancer datasets, supporting comparative analyses and protein activity inference within a unified and user-friendly environment.
