Image Dataset of Microfauna in Activated Sludge.
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
Microfauna play a crucial role in the ecological functioning and monitoring of activated sludge systems. However, existing studies often rely on manual observation and lack standardized image datasets for developing automated recognition models. Here, we present a Microfauna Dataset in Activated Sludge (MD-AS-2025), a publicly available image dataset designed to support object detection, classification, and related computer vision tasks. The dataset comprises two components: an annotated dataset (Dataset A) containing 4,000 full-frame microscopic images labeled across five morphologically and ecologically distinct microfaunal groups, and a cropped dataset (Dataset B), consisting of 14,257 single-object images generated from model-assisted detection and manual verification. All images were acquired under realistic activated sludge conditions using a high-throughput imaging system. The dataset reflects practical functional groupings commonly used in activated sludge analysis. MD-AS-2025 offers a reusable and extensible resource for developing intelligent microfauna analysis tools and provides a scalable framework for dataset construction in aquatic environments.
