85-kDa protein of Trypanosoma cruzi purified by affinity chromatography used in the multiple antigen binding assay (MABA) for the diagnosis of T. cruzi infection in a Venezuelan rural community.
Article in Parasitology research, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
No ideal test exists for Chagas' disease, and better diagnostic strategies are needed. We determined the diagnostic utility of an 85-kDa Trypanosoma cruzi protein in a multiple antigen binding assay (MABA). A standardized MABA test based on concentrated trypomastigote excretory-secretory antigen (TESA) and an 85-kDa purified protein showed 100% sensitivity and specificity. In field conditions, 6/66 individuals tested in a region not thought to be endemic (Rio Brito) were identified as seropositive for T. cruzi infection with our MABA test. In parallel, an enzyme-linked immunosorbent assay based on fixed epimastigotes detected 7/66 positives, which were independently confirmed. These data suggest that the 85-kDa and TESA proteins could be used in the MABA format as a complementary tool for the diagnosis of latent Chagas' disease. High anti-T. cruzi antibody detection rates, poor knowledge of Chagas' disease and its vector, and the demonstration of infected vectors in the study community all suggest a significant risk of reemergence of T. cruzi infection in this region of Venezuela.
