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
Domestic violence is an epidemic with profound impacts on both the mental and physical well-being of victims. In Puerto Rico, reported cases have risen rapidly in recent years, particularly after the 2020 COVID-19 pandemic. Despite its urgency, domestic violence remains understudied in the context of spatial information science, with limited research exploring how its relationship with sociodemographic factors varies across space and time. This study addresses this gap by investigating the spatiotemporal effects of domestic violence in Puerto Rico from 2020 to 2022, the COVID-19 pandemic period using geographically and temporally weighted regression (GTWR). Police-reported domestic violence data from the thirteen police regions of Puerto Rico showed a decline in 2020. Following the COVID-19 lockdown measures and mobility restrictions, it remains unknown whether this reduction is due to disruptions in reporting access and service availability or a decrease in underlying domestic violence. Results revealed statistically significant spatial clustering of police-reported domestic violence at the police-region level, with San Juan and Bayamón emerging as persistent hotspots. The female population showed strong positive associations (GTWR coefficients ranging from 0.5 to >1.0 across Puerto Rico), while separated populations exhibited moderate to strong positive relationships (0.25 to >1.0), with localized negative associations observed in the regions Aguadilla and Mayaguez. However, the population with moderate income stress demonstrated strong negative associations (coefficients < -1.0). These spatially varying relationships were not captured by the global ordinary least squares model(OLS). Overall, GTWR improved model fit (Δ Adj.
