The enigmatic role of cholinergic reflex in the pathogenesis of Chagas disease.
Article in Parasitology research, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
This study evaluated the inflammatory process in the colons of mice infected with Trypanosoma cruzi QM2 strain, through the analysis of muscle reactivity and the measurement of butyrylcholinesterase (BuChE) in plasma. "Swiss" mice were infected with T. cruzi QM2 strain and after 15 (G15), 30 (G30), 60 (G60), 90 (G90), and 210 (G210) days, each group had blood collected for the measurement of butyrylcholinesterase plasma concentrations ([BuChE]), a measure which functioned as an indicator of plasmatic Ach levels. All groups, except G15, had a segment of proximal colon removed to assess muscle reactivity to acetylcholine (Ach) and noradrenaline (NA) stimulation. After reactivity tests, the tissues were then fixed and stained with hematoxylin and eosin (HE) for histological evaluation of inflammatory response. The QM2 strain did induce inflammatory process in mice colon, and demonstrated differences in muscular contraction between the G60 and G210 groups, with p < 0.05. Plasma [BuChE] increased during the acute phase of infection (p < 0.05) with subsequent heterogeneous decline in the late chronic phase. These results show that the QM2 strain has tropism to the colon of mice and causes damage characteristic of megacolon; also, Ach has an enigmatic importance in the anti-inflammatory reflex over the course of T. cruzi infection.
