Protocol for a randomized controlled dose response trial to combat accelerated summer BMI gain in children: The Determining the Optimal amount of Structured Environments (DOSE) study.
Article in Contemporary clinical trials, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundSummer is a period of accelerated body mass index (BMI) gain for elementary school-aged children. Summer day camps may provide a structured environment, which has been shown to mitigate accelerated summer BMI gain. Many of these programs have a fee-for-service structure, creating a financial barrier for families with low-income. Providing vouchers to pay for these programs may be an effective strategy for addressing this barrier and mitigating accelerated summer BMI gain but requires further investigation on the optimal dose - the minimum exposure needed to see meaningful results while not overextending resources.
methodsThis study will use a multi-arm randomized controlled trial with three treatment levels. Children (n = 360) ages 5-12 years from participating schools (n = 4) will be randomly assigned to either summer as usual (comparison group) or to receive a voucher to attend an existing summer day camp for 4-, 6-, or 8-, weeks. BMI will be objectively measured at baseline (i.e., ∼May), 3-months (i.e., ∼August), and 12-months (i.e., ∼May of following school year). Obesogenic behaviors (e.g., physical activity, diet, screen time, and sleep) will be assessed in spring (i.e., late May) and summer (i.e., late June and July). Implementation factors, such as content, attendance frequency, duration, and coverage, relationship with children's summer BMI gain and obesogenic behaviors will also be evaluated. The study will also evaluate the cost-effectiveness of each duration. DISCUSSION: The study's findings will identify the optimal dose of summer programming to mitigate excess summer BMI gain, informing effective public health initiatives to combat childhood obesity.
