Paulinella acadia sp. nov., a New Photosynthetic Species Isolated From a Brackish Beach in British Columbia (Canada).
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 3 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
Plastids in almost all photosynthetic lineages originated from a primary endosymbiosis between cyanobacteria and heterotrophic eukaryotes in an ancestor of Archaeplastida. Strikingly, this event was repeated about a billion years later in an ancestor of photosynthetic Paulinella. Due to the recent and independent occurrence of this second primary endosymbiosis, Paulinella amoebae serve as a remarkable model group for studying the origin of plastids. To date, three species of photosynthetic Paulinella have been described mainly from freshwater and marine environments. Here, we describe a fourth photosynthetic Paulinella species from a brackish beach near Vancouver (British Columbia, Canada) using morphological and molecular data that we named Paulinella acadia sp. nov. Although P. acadia sp. nov. appears similar to P. chromatophora under light microscopy, scanning electron microscopy and molecular phylogenetic analyses demonstrate its close relationship to P. longichromatophora. The discovery of P. acadia sp. nov. expands the diversity and ecological range within this group. Notably, it is the second photosynthetic Paulinella species found on a beach to be described, alongside its sister P. longichromatophora.
