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
backgroundBehavioural interventions remain the cornerstone of evidence-based practice for addressing the core symptoms of autism spectrum disorder (ASD). The Skill Training Program for Parents with ASD Children (STPAC) is a group intervention programme for parents and the first parent-mediated intervention programme developed by Chinese clinical practitioners. This study was conducted to evaluate the feasibility and effectiveness of STPAC within the context of routine child healthcare services in China.
methodsThis is a real-world, multi-site implementation study employed a single-arm, pre-post design. Between July 2023 and June 2025, 128 families of toddlers (aged 18-54 months) with suspected or diagnosed ASD were enrolled from two child healthcare settings. Participants received the 8-week, group-based parent training programme, which integrated didactic lessons, video modelling and individualised coaching. Outcomes were assessed at baseline and post-intervention using parent-reported measures: the Knowledge of Autism Intervention Questionnaire (KAIQ), the Communication and Symbolic Behavior Scales Developmental Profile (CSBS DP) and the Parenting Stress Index-Short Form (PSI-SF). Statistical analysis included paired-samples t-tests to evaluate within-group changes, with effect sizes (Cohen's d) calculated to quantify the magnitude of improvement.
resultsParental knowledge of autism intervention strategies increased substantially (mean improvement=6.26 points, p<0.001; d=1.17). Child communication and symbolic skills also improved, with the CSBS DP total score rising from 35.30 to 40.88 (p<0.001; d=0.99), representing an overall improvement rate of 85.7%. Furthermore, parenting stress decreased from clinically significant to normal levels (mean reduction=3.70 points, p=0.005). The intervention was equally effective across diverse family demographics, and baseline child communication ability was the strongest predictor of post-intervention gains.
conclusionsDespite an attrition rate of approximately 30%, STPAC demonstrated feasibility as a parent-mediated intervention delivered by trained local clinicians within routine child healthcare settings. Participation in the programme was associated with improvements in parental knowledge, child social communication and parenting stress. These findings provide preliminary evidence supporting the potential of STPAC to expand access to early ASD intervention, though confirmation in a randomised controlled trial is warranted.
