The Chongqing Adolescent Twin Study: An Integrative Multimodal Brain Imaging and Non-imaging Dataset.
Article in Scientific data, 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
Adolescence is a pivotal phase of rapid brain development shaped by genetic and environmental factors, offering a critical window for identifying early indicators of psychiatric disorders. The Chongqing Adolescent Twin Study (CATS) explores genetic and environmental influences in 136 typically developing twins aged 12 to 19. This dataset includes multimodal MRI scans (structural, resting-state functional, and diffusion MRI) alongside extensive questionnaires on cognitive abilities, emotional and social behaviors, familial and parenting dynamics, sleep wellness, stress, anxiety, and depression. We describe the dataset in detail and systematically assess its quality. When benchmarked against the Lifespan Human Connectome Project Development (HCP-D) dataset, CATS meets or exceeds HCP-D standards in signal quality, tissue contrast, image sharpness, and head motion control. Preprocessing and imaging phenotype extraction facilitate broad reuse, and high phenotype correlations with HCP-D confirm reliability. This high-quality, multimodal resource provides a unique opportunity to investigate how genetic and environmental factors, along with age-related changes, shape adolescent brain structure, connectivity, and behavior, offering critical insights for precision medicine and early interventions in psychiatry.
