Eco-epidemiological Survey of Trypanosoma cruzi in Dogs from Mendoza, Argentina.
Article in EcoHealth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Urban domestic dog populations can provide important clues about the eco-epidemiological characteristics of Trypanosoma cruzi, the causative agent of Chagas disease (ChD). Given the limited data on ChD from the Metropolitan Area of Mendoza, Argentina, a seroprevalence survey of 327 dogs across an urban-rural gradient was conducted between April 2018 and May 2019. Seropositive cases were analyzed considering host, social, and environmental factors, subtypes (DTUs), and bloodstream parasite load. Seroprevalence of infection by T. cruzi total antigens (ELISA-H) was similar in urban (18%), interface (14%), and rural (21%) areas. Serotyping (recombinant TSSA-II antigen ELISA) revealed that 61% (37/61) of seropositive dogs carried the subtypes TcII, V and/or VI. There was no difference in the proportion of seropositive dogs versus seronegative dogs that lived with a person with ChD (9/62 = 14% vs. 35/265 = 13%, respectively). Parasite loads in seropositive dogs varied between < 0.10 and 1.18 parasite-equivalents/ml. Dogs with T. cruzi infection were in good health and nutritional condition, suggesting that they may have indeterminate or chronic stage infections. High infection rates in all areas and limited knowledge of owners about ChD and its triatomine vectors emphasize the need to intensify entomological studies, especially in urban areas, and promote vector information campaigns. This work shows that screening of dogs is a beneficial epidemiological tool to deepen studies on ChD from a One Health perspective.
