Investigating Socioeconomic Disparities in Park Access Across Two Southeastern US Cities Using a Unique Park Metric: An Ecological Analysis.

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
PurposeThis study aimed to demonstrate how ParkIndex values can be used to examine issues related to composite park access, and to investigate whether ParkIndex scores for block groups were significantly different by income, race/ethnicity, and population density.DesignCross-sectional, environmental justice analysis of spatial disparities.SettingGreenville County, South Carolina, and Raleigh, North Carolina.SubjectsPark access and quality data were collected for a total of 507 block groups across the study setting.MeasuresFor all study block groups, we empirically derived a multi-dimensional park access metric called ParkIndex representing the probability of park use based on three park availability and quality indicators. Block group median household income, race/ethnicity, and population density were obtained from the US Census Bureau's American Community Survey.AnalysisChoropleth maps were used to juxtapose ParkIndex values and neighborhood sociodemographic attributes. Analysis of variance was conducted to examine differences in ParkIndex values by multiple sociodemographic variables.ResultsNo significant differences in ParkIndex values were found by median household income (F = 0.15,
