1 · What the graph read from it

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.

2 · The registry

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

Kinetoplastids are a large and diverse protist group, spanning ecologically important free-living forms to medically important parasites. The taxon Allobodonidae holds an unresolved position within kinetoplastids, and the sole described species, Allobodo chlorophagus, is uncultivated, being a necrotroph/parasite of macroalgae. Here we describe Allobodo yubaba sp. nov. and Novijibodo darinka gen. nov. et sp. nov., both free-living bacterivores isolated into monoeukaryotic cultures. Electron microscopy shows that both A. yubaba and N. darinka have a microtubular prism in the feeding apparatus (absent in A. chlorophagus), and an ovoid eukinetoplast, rather than pan-kDNA as in A. chlorophagus. Phylogenetic analyses of SSU rDNA sequences robustly place A. yubaba as the sister to A. chlorophagus, while N. darinka branches separately within Allobodonidae, as a sister group of undescribed freshwater isolates. We view Allobodonidae as containing at least four genus-level clades: Allobodo (A. chlorophagus and A. yubaba n. sp.), an undescribed fresh-water clade, an undescribed marine clade, and now Novijibodo-with N. darinka as its sole known member. Electron microscopy also revealed a rod-shaped gram-negative bacterial cytoplasmic endosymbiont in our N. darinka isolate. The availability of these species in monoeukaryotic culture should facilitate future research, including resolving the position of Allobodonidae using phylogenomic approaches.
