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
Background: Independent mobility in early life catalyzes development across motor, perceptual, cognitive, social, and linguistic domains. For young children with motor disabilities, however, opportunities to explore, interact, and learn from their surroundings are commonly restricted, which may limit developmental progress. Objective: To examine the effects of a play-based powered mobility intervention, using the Permobil Explorer Mini, on developmental and communicative outcomes in toddlers with motor disabilities, using a single-group, repeated measures design. Methods: Ten children with motor disabilities (ages 12-36 months) participated in a 12-session intervention in an enriched laboratory environment. The intervention consisted of repeated, play-based sessions using the Explorer Mini, an FDA-cleared powered mobility device. Developmental skills were evaluated pre- and post-intervention using standardized assessments, and language environments were systematically analyzed both in the laboratory and at home. Results: At baseline, participants scored significantly below age-matched norms across all domains (gross and fine motor, receptive and expressive language, cognitive, adaptive behavior, and social-emotional). Following the intervention, children showed significant raw score gains in cognition, receptive language, fine motor, adaptive behavior, and social-emotional development. Scaled score improvements in cognition and receptive vocabulary indicated growth exceeding expected age-related progression. Analyses of the language environment revealed significant increases in children's expressive vocalizations. Specifically, more frequent joyful ("delight") vocalizations and fewer expressions of distress. Increases in delight vocalizations were further strongly correlated with receptive language gains. Conclusion: These findings suggest that introducing powered mobility during the toddler period can foster agency, exploration, and communication, catalyzing developmental growth beyond motor function alone. By providing young children with the means to move independently, powered mobility may open new pathways for participation, learning, and connection, laying critical groundwork for more equitable developmental opportunities in early childhood.
