Benznidazole Use among Patients with Chronic Chagas' Cardiomyopathy in an Endemic Region of Brazil.
Article in PloS one, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Chagas disease (CD) is a neglected tropical disease that affects individuals in almost every country in Latin America. There are two available drugs with antiparasitic profiles; however, only benznidazole (BZN) has been approved for commercialization in Brazil. The usefulness of prescribing BZN for patients with chronic Chagas cardiomyopathy (CCC) is controversial. There are no studies in the literature describing the extent of BZN use at this stage or the profile of patients using this drug. The present study aimed to determine the prevalence and factors associated with previous BZN use among individuals with CCC. This cross-sectional study was conducted with 1,812 individuals with CCC from 21 Brazilian cities endemic for CD. The dependent variable was "prior use of BZN" (no vs. yes). The independent variables were grouped into socioeconomic, lifestyle and medical history aspects. Binary logistic regression (α ≥ 0.05) was used. Among the evaluated individuals, 27.2% reported previous use of BZN. The likelihood of prior use of BZN was higher among younger individuals (OR = 2.7), individuals with a higher education (OR = 2.7), individuals with a lower monthly per capita income (OR = 1.3), individuals who practiced physical exercise (OR = 1.5), individuals who had prior knowledge of the CD diagnosis (OR = 2.5), individuals without hypertension (OR = 1.3) and individuals with a longer time to the CD diagnosis (OR = 6.1). The present study revealed a small proportion of therapeutic BZN use among Brazilian CCC patients. This finding suggests a late diagnosis and undertreatment of the disease. BZN use was higher among individuals with better clinical and demographic conditions but with a lower income and a longer time to the CD diagnosis. Knowledge of the BZN usage profile may help reduce the current state of neglect of this disease and pave the way for future studies.
