The Park Rx trial to increase physical activity among low-income youth.
Trial report in Contemporary clinical trials, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04114734 (Park Rx, Physical Activity and Other Health Benefits Among Low-income Children), which is not on this map. Cited by 7 papers.
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.

Abstract
backgroundThe Park Rx study is a prospective, randomized controlled trial implemented within a federally qualified health center serving a low-income population in Washington, DC. DESIGN AND
settingThe 5-year randomized controlled trial will recruit 500 children, ages 6-16 to be randomized to receive either a park prescription (Park Rx) during routine clinical visits (intervention arm) or care as usual (control arm).
interventionPark prescriptions promote both physical activity and exposure to nature. The prescription includes a place (i.e., park), an activity, a frequency, and a duration. Compared to usual care, we expect children receiving a park prescription will have greater physical activity levels and improved physical and mental health outcomes. IMPLICATIONS: The results of the Park Rx trial will demonstrate the efficacy of the intervention and whether it will increase time spent in nature-rich areas (i.e., parks); have any biological impacts on health, including reducing hypercholesterolemia, hypertriglyceridemia, HbA1c, body mass index (BMI), and impact mental health, including stress and cognitive functioning.
