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

Euglenids are microbial flagellates best known for their highly flexible photosynthetic species (e.g., Euglena gracilis), though many heterotrophic groups remain poorly characterized at both molecular and ultrastructural levels. In particular, rigid heterotrophs such as ploeotids and petalomonads are highly diverse, yet most described species were documented only with light microscopy, largely because they are difficult to cultivate. Here, we establish cultures for three new isolates of ploeotids and petalomonads (Hokulea pusilla comb. nov., Ploeotia protuberantia sp. nov., Scytomonas flumensis sp. nov.) and examine them using light microscopy, scanning electron microscopy, and 18S rDNA phylogenetic analyses. These data support the recognition of two new species, Ploeotia protuberantia sp. nov. and Scytomonas flumensis sp. nov., and justify the transfer of Ploeotia pusilla to Hokulea pusilla comb. nov. based on its morphology and its affiliation with Hokulea waialensis in 18S rDNA phylogenies.
