A Multigene Perspective on the Phylogeny and Evolutionary Relationships of Class Spirotrichea (Ciliophora).

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
Despite extensive research, evolutionary relationships within the class Spirotrichea remain contentious due to limitations of single-gene phylogenies and sparse molecular data. This study provides the first comprehensive phylogenomic framework integrating four molecular markers (SSU-rRNA, ITS1-5.8S-ITS2, LSU-rRNA, mtSSU-rRNA), morphological traits, and dual rRNA secondary structures, resolving long-standing taxonomic conflicts. Key advances include: (1) Critical expansion of underrepresented molecular data: 19 novel mtSSU-rRNA sequences generated for Spirotrichea, a gene previously scarce in this class, enabling robust phylogenetic reconstruction. (2) Redefinition of major evolutionary lineages: Spirotrichea is restructured into four distinct clades: (i) Subclass Euplotia (excluding Discocephalida); (ii) Subclasses Hypotrichia + Oligotrichia + Order Discocephalida; (iii) Subclasses Protohypotrichia + Phacodinidia; (iv) Subclass Licnophoria as the earliest-diverging lineage. (3) Resolution of key taxonomic uncertainties: Certesiidae as the sister group of Euplotidae. Discocephalida is reclassified as an evolutionary pivot linking Euplotia and Hypotrichia, evidenced by ITS2 Type 4 architecture and ciliary homologies.
