Scientific production on health inequalities using the Brazilian Information System on Live Births: a scoping review.
Article in Cadernos de saude publica, 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 Brazilian Information System on Live Births (SINASC) is widely used by health managers to plan and monitor maternal and child health programs. Scientific research using SINASC data is also essential to identify underexplored topics that warrant further investigation. This study aims to describe the profile of scientific output based on SINASC data and to determine gaps in the literature, with particular attention to studies addressing health inequalities. A scoping review was conducted, including original articles reporting primary outcomes derived from SINASC data. Five databases were searched up to August 2025: PubMed, Embase, Scopus, Web of Science, and LILACS. Brazilian official websites were also manually consulted. A total of 7,363 records were identified, and 85 studies were included in the final analysis. The most frequently analyzed variables were congenital anomalies, birth weight, pregnancy duration, type of delivery, and maternal age. The most commonly reported outcomes were cleft lip/palate, prematurity, low birth weight, Cesarean section, and maternal age distribution. Almost all studies (95.3%) addressed at least one inequality dimension, most frequently geographic and maternal sociodemographic factors. The Human Development Index was the main external socioeconomic indicator. This review underscores the relevance of SINASC for advancing research on health equity in Brazil. Nonetheless, gaps remain in analyses of antenatal care and race/skin color.
