Specialist-mediated play therapy for toddlers with language developmental delay: a single-center observational pilot study.
Article in Frontiers in rehabilitation sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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: Language developmental delay is one of the most common neurodevelopmental concerns in early childhood. Early intervention is considered critical for improving communication outcomes, yet the comparative effectiveness of different intervention approaches remains incompletely understood. Objective: To examine the association between three early intervention strategies, clinic-based structured language rehabilitation, parent-led family intervention, and specialist-mediated play therapy, and language developmental outcomes in toddlers with mild language developmental delay in a non-randomized observational design. Methods: This single-center case-control observational pilot study included 180 children aged 18-36 months diagnosed with mild language developmental delay using the Gesell Developmental Diagnosis Scale. No randomization was performed. Participants were categorized into three intervention groups according to the clinical management strategy selected following standardized physician consultation and parental preference: clinic-based structured language rehabilitation ( Results: Language DQ improved significantly over time in all three groups ( Conclusion: Early intervention was associated with improvements in language development among toddlers with mild language delay. Specialist-mediated play therapy demonstrated a stronger association with language gains compared with clinic-based structured rehabilitation and parent-led interventions. These findings demonstrate association rather than causation owing to the non-randomized observational design. Further large-scale, multicenter randomized controlled trials are required to confirm these findings, establish causal efficacy, and determine optimal early intervention strategies.
