1 · What the graph read from it

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.

2 · The registry

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

Microplastic contamination has emerged as a growing concern for soil ecosystems and their ecological functioning. However, the effects of microplastic contamination in fragile plateau wetlands remain poorly understood. In this study, biodegradable polylactic acid (PLA) and conventional polypropylene (PP) MPs were compared using soil seed bank collected from terrestrial and hygrophytic habitats in the Xingyun Lake plateau wetland. Seed germination, species diversity, and soil chemical properties were evaluated. Habitat specific effects were observed, and PLA induced stronger inhibition of seed germination and diversity than PP. These findings underscore the need to incorporate plant ecological responses, including germination physiology under chemical stress and soil seed bank dynamics, into ecological risk assessments of MPs. Furthermore, MP associated changes in nutrient dynamics and soil chemistry were examined, providing insight into potential long-term implications for plateau wetland restoration and plant community recovery.
