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

Metamonads are a large and exclusively anaerobic group of protists. Additionally, they are one of the three clades proposed to ancestrally possess an "excavate" cell morphology, with a conspicuous ventral groove accompanied by a posterior flagellum with a vane. Here, we cultivate and characterize four anaerobic bacterivorous flagellates from hypersaline and alkaline soda lake environments, which represent a novel clade. Small subunit ribosomal RNA (SSU rRNA) gene phylogenies support recent phylogenomic analyses in placing them as the sister of barthelonids, a group that is itself sister to or deeply branching within Fornicata (Metamonada). The new isolates have a distinctive morphology: the hunchbacked cell body is traversed by a narrow ventral groove ending in a large opening to a conspicuous recurrent cytopharynx. The right margin of the groove is defined by a thin "lip." The posterior flagellum bears a wide ventral-facing vane. The narrow ventral groove and elongate cytopharynx are shared with barthelonids. We describe one isolate as Skoliomonas litria, gen. et sp. nov. Further investigation of their mitochondrial-related organelles (MROs) and detailed ultrastructural studies would be important to understanding the adaptation to anaerobic conditions in Metamonads-especially fornicates-as well as the evolution of the "excavate" cell architecture.
