Does the Gonostomum-patterned oral apparatus in hypotrichia carry a phylogenetic signal? Evidence from morphological and molecular data based on extended taxon sampling using three nuclear genes (Ciliophora, Spirotrichea).

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
The classification of hypotrichs based on the gonostomatid oral structure is widely accepted, but the phylogenetic signal of this character is unknown. Here, we infer the species phylogeny of those gonostomatids for which molecular data are available, plus 26 new sequences of SSU-rDNA, ITS1-5.8S-ITS2 and LSU-rDNA genes. The results indicate that: (i) the endoral is more phylogenetically informative than the paroral; (ii) the structure of the endoral and the Gonostomum-pattern adoral zone of membranelles are plesiomorphies for the hypotrichs sensu stricto; (iii) the group of species possessing these features is monophyletic in all our phylogenetic analyses, except that for the SSU-rDNA; (iv) Schmidingerotrichidae is monophyletic in all trees, suggesting that it is a well-defined family; (v) the Gonostomatidae is polyphyletic in the SSU-rDNA and ITS1-5.8S-ITS2 trees, with Gonostomum, Cladotricha, Cotterillia, Metagonostomum, Paragonostomum and Wallackia distributed among separate clades, but monophyletic in the LSU-rDNA and concatenated trees; (vi) higher hypotrich taxa such as core urostyloids and core sporadotrichids/stichotrichids might have evolved from species that possessed a gonostomatid oral apparatus.
