Trypanosoma cruzi infection status in birthing individuals in three endemic provinces of Argentina: a descriptive cross-sectional study.
Article in Revista da Sociedade Brasileira de Medicina Tropical, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundChagas disease remains a public health challenge with underexplored prevalence and diagnosis in endemic areas. We assessed Trypanosoma cruzi infection screening among birthing individuals in three endemic provinces in northern Argentina.
methodsT. cruzi-seropositive birthing individuals with at least one positive or indeterminate test were enrolled during the postpartum period to confirm seropositivity by indirect hemagglutination (IHA) and enzyme-linked immunosorbent (ELISA) assays.
resultsAmong 40,035 deliveries, the T. cruzi infection rate was 1.9%. Confirmatory serology revealed 77.6% positivity, 9.3% negativity, and 13.0% discordance.
conclusionsThese findings highlight the need for confirmatory testing and improved diagnostic strategies in endemic regions.
