PACO: a Shiny app for comparing perturbed pathways associated with different phenotypes.
Article in Bioinformatics advances, 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
Motivation: Pathways are biological networks describing interactions between genes, proteins, non-coding RNAs, drugs and chemical compounds that contribute to develop a specific metabolic function or biological process. Identifying perturbed pathways associated with a phenotype or condition helps to understand how functional processes are altered in complex diseases and which genes play a key role in these alterations. Recently, several algorithms have been developed to identify perturbed pathways associated with a phenotype. Still, no tools are available to visualize and compare perturbed pathways in the same species or different organisms. Results: Here, we present a web app called PAthway COmparator (PACO) to compare two or more sets of altered pathways associated with different phenotypes, starting from either custom data or simulation data returned by the pathway analysis algorithms MITHrIL and PHENSIM. The app allows users to visualize and compare the altered pathways, and zoom into specific regions. We show the potential applicability of PACO through a case study in which perturbed immune system pathways are compared in mice and humans after up-regulation of Interferon-stimulated gene 15 (ISG15). Availability and implementation: PACO is implemented as a Shiny R web application and is available at https://paco.dioncogen.eu/.
