Prevalence of Maternal Chagas Disease and Vertical Transmission Rates in Bolivia: A Systematic Review and Meta-Analysis.

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
Bolivia has one of the highest burdens of Chagas disease in the world. Vertical transmission from mother to infant accounts for a growing number of cases. We performed a systematic review of articles assessing the prevalence of Chagas disease in pregnant women and rates of vertical transmission to infants in Bolivia. Studies were not excluded based on year of publication or language. Random-effects analyses were performed to estimate a pooled prevalence of maternal Chagas disease and pooled vertical transmission rate. Our search yielded 21 articles describing over 400,000 cases of Chagas disease among pregnant women in Bolivia. The reported prevalence of maternal Chagas disease ranged from 17.3% to 64.5%, with a pooled prevalence of 33.0% (95% CI, 27.4-38.7%). The prevalence of maternal Chagas disease trended down over time (P = 0.006), decreasing by approximately 25% to 30% over the last 40 years. Vertical transmission rates ranged from 2.0% to 13% with a pooled average of 6.2% (95% CI, 4.4-7.5%); rates did not significantly change over time. Our study is the first systematic review and meta-analysis of Chagas disease maternal prevalence and vertical transmission in Bolivia. Our findings indicate that maternal Chagas disease has fallen in prevalence but still affects 20% to 30% of pregnant women and poses a considerable risk of vertical transmission. Pregnant women and infants are an important target for public health interventions to limit the mortality and morbidity of Chagas disease and to reduce intergenerational spread.
