Interventions to Promote Communication in Minimally Verbal Autistic Children: A Systematic Review.
Synthesis in Medical sciences (Basel, Switzerland), 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/
objectivesMinimally verbal autistic children face profound communication challenges that significantly affect daily functioning, including social interaction, behavioral regulation, and overall well-being. Identifying effective interventions is a key clinical-educational priority. This systematic review examines communication-focused interventions for these children, including both spoken language approaches and augmentative and alternative communication (AAC) strategies.
methodsThe review was registered in PROSPERO and conducted following PRISMA-S guidelines. Four electronic databases were searched, and 18 studies met the inclusion criteria. Due to heterogeneity in study designs and outcome measures, a narrative synthesis was conducted, with subgroup analyses exploring sample characteristics, intervention types, targeted outcomes, and reported effects. Methodological quality of randomized controlled trials was assessed using the Cochrane Risk of Bias tool.
resultsInterventions were implemented across clinical, educational, and home settings, using strategies such as Joint Attention, Symbolic Play, and Emotion Regulation, often combined with AAC technologies. Most included studies reported improvements in at least one communication outcome, although findings were heterogeneous and several studies reported mixed, subgroup-specific, or non-significant effects. The most consistent improvements were observed in spontaneous communication, particularly in interventions integrating developmental approaches with technological support.
conclusionsThese findings highlight the value of individualized interventions. Future research should establish standardized definitions of "minimally verbal", assess long-term outcomes, and adopt broader measures capturing both language and social-emotional development to enhance quality of life and inclusion.
