Impact of congenital syphilis incidence on congenital heart surgery outcomes in Brazil.

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
This study examines the impact of congenital syphilis incidence trends on congenital heart surgery outcomes in Brazil, with a focus on mortality rates, treatment costs, and length of hospital stay. Using an ecological study design, we analyzed nationwide data from 2007 to 2023 to identify regional and temporal patterns in these relationships. The results revealed significant increases in the incidence of syphilis across all regions, accompanied by marked disparities in healthcare resource allocation and surgical capacity. The Northeast and Southeast regions demonstrated expansion in approved surgeries, while the North and South regions exhibited comparatively slower growth, highlighting inequities in specialized care access. Correlation analyses identified a moderate negative association between syphilis incidence and mortality rate, and a strong negative correlation between cost per surgery and mortality. Our regression model explained 44.2% of the variance in mortality rates, with syphilis incidence, cost per surgery, and length of hospital stay emerging as significant predictors. Machine learning validation confirmed the predominance of linear relationships, with Linear Regression (
