Reinvigorating the Promise of the National Database for Autism Research (NDAR) to Advance Autism Knowledge.
Article in Journal of autism and developmental disorders, 2025. 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
The National Institute of Mental Health created the National Database for Autism Research (NDAR) to accelerate autism knowledge through data sharing and collaboration. However, our experience using NDAR reveals systematic challenges across several aspects of data submission, selection, management, and analysis that limit utility of this resource. We describe our NDAR experience in an ongoing project examining autism intervention outcomes among marginalized racial, ethnic, and gender groups. For this study, we planned to gather data from NDAR to conduct an individual participant data meta-analysis. Eighteen studies met inclusion criteria and reported data on participants at more than one point in time on the Vineland Adaptive Behavior Scales (Vineland) and the Autism Diagnostic Observation Schedule (ADOS). The difficulties with submitting, selecting, downloading, and managing data from NDAR posed limitations on data availability and analysis. Of the 3,850 unique participants in the selected studies, data at multiple time points were available for 312 participants on the Vineland and 278 on the ADOS. No participants had data on all assessment domains. To accelerate autism research via data sharing and collaboration with NDAR necessitates improving the processes for submitting, selecting, and managing data.
