Tritrichomonas foetus pseudocysts adhere to vaginal epithelial cells in a contact-dependent manner.
Article in Parasitology research, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
Tritrichomonas foetus is a parasitic protist of the urogenital tract of cattle. It presents the trophozoite stage, a motile elongated form that constitutes most of the cells in a normal population, and a pseudocyst stage, an immotile rounded form that appears under unfavourable environmental conditions. In the present report pseudocysts were studied in natural conditions and after induction by chemicals or cycles of cooling and warming of cultures. The capacity of T. foetus to adhere to vaginal epithelial cells (VECs) was compared for both trophozoite and pseudocyst forms. By the use of video-enhanced-contrast microscopy, scanning and transmission electron microscopy, and immunofluorescence microscopy techniques, we present evidence that: (1) T. foetus easily internalizes the flagella and forms pseudocysts under several unfavourable conditions; (2) T. foetus in both pseudocyst and trophozoite forms is able to adhere to VECs; (3) the adhesion rate is higher for pseudocysts than for trophozoites; (4) the adhesin Tf190 is expressed in both forms during interaction; (5) the adhesion process of pseudocysts seems to occur in a contact-dependent manner. Thus, we propose that the pseudocyst stage is not a degenerative form, but a functional life form that is able to interact with and firmly adhere to VECs.
