Retention, blinding, and health outcomes from a rural pediatric obesity feasibility randomized control trial.
Trial report in Journal of pediatric psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04142034 (Feasibility Trial of the iAMHealthy Intervention for Healthy Weight in Rural Children Recruited From Primary Care Clinics), which is not on this map. Not yet cited in PubMed.
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
objectiveTo evaluate the feasibility of a multi-state randomized control trial (RCT) evaluating iAmHealthy, a rurally tailored pediatric obesity treatment delivered via synchronous televideo. This study's primary outcomes included the evaluation of participant retention and the efficacy of blinding. Each intervention arm was hypothesized to retain >75% of randomized participants and preserve blinding. Additionally, the intervention's preliminary effectiveness was evaluated by comparing changes in health outcomes.
methodsYouth aged 6-11 years with a body mass index (BMI) percentile ≥85th and their caregivers were recruited from rural communities across four states participating in the Environmental Influences on Child Health Outcomes IDeA States Pediatric Clinical Trials Network. One hundred four dyads were randomly assigned to iAmHealthy plus newsletter or newsletter-only control. Retention rates for each treatment arm were calculated. Blinding was assessed via the New Blinding Index (NBI). Child and parent BMI, child physical activity, and child dietary intake were assessed at baseline and post-treatment (6 months).
resultsA one-sample test of proportions indicated retention rates exceeded 75% for iAmHealthy (87%, p = .027) and control (96%, p < .001). Blinding was successful for both groups [iAmHealthy NBI = -0.12, 95% confidence interval (CI): -0.13 to 0.36; control NBI = 0.02, 95% CI: -0.24 to 0.28]. There were no significant differences in health outcomes.
conclusionsThis iAmHealthy multi-state feasibility RCT demonstrated high retention and successful blinding of assessors. Although the study was not powered to detect health outcome differences, iAmHealthy exhibited a tendency toward greater improvement or attenuated declines in child health outcomes, which supports the conduct of a future fully powered RCT.
