ChildLens: An egocentric video dataset for activity analysis in children.
Article in Behavior research methods, 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
We present ChildLens, an egocentric video and audio dataset with detailed annotations for activities of naturalistic everyday experiences in children aged 3 to 5 years. A total of 109 h were recorded from 62 children in their home environment using a 140° wide-lens camera equipped with a microphone integrated in a child-friendly vest. Annotations include five location classes and 14 activity classes, covering audio-only, video-only, and multimodal activities. Good benchmark performance of two state-of-the-art models on the dataset-the Boundary-Matching Network for temporal activity localization and the Voice Type Classifier for detecting and classifying speech in audio-speak to the quality of the annotations. The ChildLens dataset will be freely available for research purposes via an institutional repository. It provides rich data to advance computer vision and audio analysis techniques and thereby removes a critical obstacle to studying the everyday context of child development, listed on the ChildLens website: https://www.eva.mpg.de/comparative-cultural-psychology/technical-development/childlens/ .
