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

Landfills serve as a significant source of microplastics (MPs) contamination, affecting the surrounding air, water, and agricultural soils. This study examined the seasonal variation of MPs in leachate, river water, and soil at Sisdole (old) and Banchare Dada (new) landfill sites (LFSs). MPs greater than 90 μm were enumerated using a stereomicroscope, and polymer identification was performed on a representative subset of particles using micro-Fourier transform infrared (FTIR) spectroscopy. Average MPs concentrations were higher at the new landfill, with values of 56 ± 07 MPs/L at Banchare Field and 44 ± 27 MPs/L at Banchare Tank, compared to 28 ± 11 MPs/L at Sisdole Pond in the old landfill. In river water, MPs increased downstream: 17 ± 12 MPs/L at Sisdole Upstream, 28 ± 22 MPs/L at Sisdole Downstream, and 34 ± 06 MPs/L at Banchare Downstream. Soil contamination was highest at Sisdole (351 ± 173 MPs/100 g), followed by Banchare (214 ± 70 MPs/100 g) and Banchare-Sisdole (157 ± 48 MPs/100 g). Statistical analyses, including a paired
