Rationale and methods of the MOVI-HIIT! cluster-randomized controlled trial: an avatar-guided virtual platform for classroom activity breaks and its impact on cognition, adiposity, and fitness in preschoolers.
Article in Frontiers in digital health, 2026. 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
Introduction: Classroom-based active breaks (ABs) have been shown to reduce sedentary time and increase physical activity in primary school children; however, evidence regarding their effects on body composition, physical fitness, cognition and other health-related outcomes remains limited in preschool children. This article describes the rationale and prespecified methods of the MOVI-HIIT study, a cluster-randomised controlled trial (RCT) evaluating a classroom-based, HIIT-inspired ABs intervention delivered through a gamified digital platform to improve body composition, physical fitness, and cognition in children aged 4-6 years. In addition, we outline a nested qualitative study designed to explore teachers' perceptions of barriers and facilitators to programme implementation and monitoring. Methods: A RCT was conducted in nine schools in the province of Ciudad Real, Spain. Schools were randomly assigned to the MOVI-HIIT intervention group ( Discussion: MOVI-HIIT represents the first intervention in early childhood education to integrate HIIT-based ABs with a gamified digital platform. Its structured, high-intensity exercise, combined with a mixed-methods process evaluation, may provide an innovative and potential reproducible model that can strengthen the evidence on classroom-based physical activity and contribute to creating active and healthy educational environments from early childhood onwards.
