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
An understanding of the relationships between plastics and plasticizers is vital in order to assess their environmental risk. We investigated spatial trends and relationships between microplastics and plasticizers in sediments of an urbanized estuary subject to contemporary and historic sources of contamination (Forth estuary, Scotland, UK). As such, this study represents one of the first to investigate the co-occurrence of emerging plasticizers, phthalates, and microplastics in an estuary system. We determined the concentration of 7 legacy (phthalate) and 3 emerging (adipate, terephthalate, trimellitate) plasticizers and 21 microplastic polymer types. The most abundant microplastics were polyethylene (PE), polypropylene (PP), polyurethane (PU), and poly(vinyl chloride) (PVC). Plasticizers were dominated by diethylhexyl phthalate (DEHP), although emerging plasticizers (e.g., diethylhexyl terephthalate, DEHTP) were frequently detected at low concentrations (mean 7.3 ng g
