How much neighborhood parks contribute to local residents' physical activity in the City of Los Angeles: a meta-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
objectiveTo quantify the contribution of neighborhood parks to population-level, moderate-to-vigorous physical activity (MVPA).
methodWe studied park use in 83 neighborhood parks in Los Angeles between 2003 and 2014 using systematic observation and surveys of park users and local residents. We observed park use at least 3-4 times per day over 4-7 clement days. We conducted a meta-analysis to estimate total, age group and gender-specific park use and total MVPA time in parks.
resultsAn average park measuring 10 acres and with 40,000 local residents in a one-mile radius accrued 5301 h of use (SE=1083) during one week, with 35% (1850 h) spent in MVPA and 12% (635 h) spent in vigorous physical activity (VPA). As much as a 10.7-fold difference in weekly MVPA hours was estimated across study parks. Parks' main contribution to population-level MVPA is for males, teenagers, and residents living within a half mile.
conclusionNeighborhood parks contribute substantially to population MVPA. The contribution may depend less on size and facilities than on "demand goods" - programming and activities--that draw users to a park.
