A Deeply Branching Lineage in Heterolobosea (Discoba) With Multiflagellated and Multigrooved Life Stages.
Article in The Journal of eukaryotic microbiology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Several distantly related, deep-branching lineages within the eukaryotic tree of life share what is known as the "typical excavate" morphology. This cell architecture includes a suspension-feeding ventral groove, supported by complex and specific structures of the cytoskeleton, and a vane-bearing posterior flagellum. Within Discoba, such characteristics were found only in the deepest branch, Jakobida, also famous for having the most gene-rich and bacterial-like mitogenomes. Some members of the discoban lineage Heterolobosea also possess a ventral groove. However, they lost many other typical excavate characteristics, including the flagellar vane and some flagellar root elements. We have established a clonal culture of a free-living freshwater flagellate from Malaysia, strain NY0229, described here under the provisional name Multisulcus malaysiensis nom. prov. Electron microscopy observations show a conspicuous ventral groove reinforced with microtubules of the flagellar apparatus and a vane on the posterior flagellum. Strain NY0229 has typical excavate biflagellated forms but also exhibits very atypical multiflagellated and multigrooved forms. The kinetid consists of two orthogonally oriented kinetosomes; both flagella of biflagellate cells display proximal and distal projections. Molecular phylogenetic analyses support a deep-branching position of the new strain within Heterolobosea, as the sister lineage to all previously known Eutetramitia.
