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
objectiveThis ecological study analyzes the temporal evolution of female homicide rates in the state of São Paulo, Brazil, from 1980 to 2022, using data from the Mortality Information System (SIM).
methodsPossible change points in the trend of these rates were identified using the Bayesian Estimator of Abrupt Change, Seasonality, and Trend (BEAST) model.
resultsA total of 29,234 female homicide cases were recorded during the period, including 3,914 among young women aged 15 to 19. The analysis detected two major change points in 1995 and 2004, dividing the time series into three segments: an increasing trend until 1994, a stable period from 1995 to 2003, and a decreasing trend from 2004 onward. Among young women, three change points were identified, with a significant and consistent decline in homicide rates from 2004 to 2022.
conclusionThe number of female homicides in São Paulo has declined significantly since 2004, particularly among young women aged 15-19. Although this is linked to policy changes, the decline is likely due to multiple factors. The study highlights the importance of ongoing gender-focused policies and robust analytical tools in guiding public safety efforts.
