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

Thecate amoebae play important roles in terrestrial and aquatic ecosystems. This study introduces a novel thecofilosean amoeba from Arctic and Antarctic sea sediments. Phylogenetic analysis based on the 18S rDNA sequence places it in the family Chlamydophryidae (order Tectofilosida, class Thecofilosea). However, the novel organism exhibits a significant genetic divergence and distinct morphology from its closest relatives, prompting us to erect the novel genus Katarium with its type species Katarium polorum. K. polorum is a consumer of diatoms and prokaryotes, indicating an important role in nutrient cycling in the polar marine food webs.
