Trypanosoma cruzi infection in pregnancy: New approaches to address the diagnosis and follow-up of women and newborns.
Review in PLoS neglected tropical diseases, 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
The transplacental route is the main human-to-human transmission mode of Trypanosoma cruzi infection, causing congenital Chagas disease, a major health problem in most endemic and nonendemic areas. The prevention, diagnosis, and follow-up of pregnant women and congenitally infected newborns face limitations, such as regional variations of concordance among serological tests used to diagnose T. cruzi infection in the Americas, the low sensitivity of microscopic examination for detecting live trypomastigotes in blood, and losses of infected women and newborns in screening and follow-up programs. In addition, fetal growth retardation was recently documented in uninfected newborns of infected mothers. The potential practical impacts of some new approaches, based on fundamental concepts and results of clinical observations addressing T. cruzi infection in pregnancy, such as simplifying the serodiagnosis, detecting and identifying live T. cruzi clones and monitoring fetal growth retardation in all neonates of infected mothers, are discussed as open research questions.
