Mechanics of Microsporidian Polar Tube Firing.
Article in Experientia supplementum (2012), 2022. 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
As obligate intracellular parasites with reduced genomes, microsporidia must infect host cells in order to replicate and cause disease. They can initiate infection by utilizing a harpoon-like invasion organelle called the polar tube (PT). The PT is both visually and functionally a striking organelle and is a characteristic feature of the microsporidian phylum. Outside the host, microsporidia exist as transmissible, single-celled spores. Inside each spore, the PT is arranged as a tight coil. Upon germination, the PT undergoes a large conformational change into a long, linear tube and acts as a tunnel for the delivery of infectious cargo from the spore to a host cell. The firing process is extremely rapid, occurring on a millisecond timescale, and the emergent tube may be as long as 20 times the size of the spore body. In this chapter, we discuss what is known about the structure of the PT, the mechanics of the PT firing process, and how it enables movement of material from the spore body.
