Identifying missed prevention opportunities: maternal and congenital syphilis in hospital records and birth certificates in California from 2011 to 2021.

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
objectiveTo examine maternal risk factors for congenital syphilis (CS). STUDY
designWe used a retrospective, population-based cohort of births in California (2011-2021) with linked birth certificates and hospital records. Modified Poisson regression models with robust standard errors were used to assess characteristics associated with CS. Among dyads with CS, maternal syphilis documentation was also examined.
resultsOf 4,481,096 births, 4659 (0.1%) had maternal syphilis without CS, and 2608 (0.06%) had both maternal syphilis and CS. CS was associated with having public insurance, tobacco use, drug use disorders, and residence in fringe-metro or medium/small-metro counties. Among CS dyads, 62.0% had no maternal syphilis documentation. There was a lower risk of no maternal syphilis documentation among those with <12th grade education; non-Hispanic Black identity; tobacco, cannabis, or drug use disorders; mental health conditions; and inadequate prenatal care.
conclusionsUniversal prenatal syphilis screening, treatment, and documentation are essential to preventing CS.
