Colchicine treatment reversibly blocks cytokinesis but not mitosis in Trypanosoma cruzi epimastigotes.
Article in Parasitology research, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
This work analyzes the effect of the alkaloid colchicine on the growth of Trypanosoma cruzi epimastigotes, using immunofluorescence microscopy and flow cytometry techniques. We found that colchicine reversibly inhibited cytokinesis but not synthesis or segregation of nuclear and kinetoplastid DNA, in a concentration-dependent manner. We showed that, once colchicine was removed from the growth medium, cytokinesis was restored but abnormal segregation of kinetoplasts and nuclei generated zoids and parasites with two nuclei and one kinetoplast, among other aberrant cells. After drug removal, we also observed a few anucleated cells carrying two kinetoplasts in a stage compatible with the end of cytokinesis. The anomalous subcellular localization of the kinetoplast and flagellum observed in treated parasites suggests that the effect of colchicine and its interaction with T. cruzi microtubules is cell cycle dependent. The crosstalk between nuclear and kinetoplastid mitosis and its incidence on flagellum growth and parasite cell division regulation are discussed.
