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

This study investigated the biotransformation of three different plastic surfaces, polypropylene (PP), polyvinyl chloride (PVC) and polyethylene (PE), by anaerobic digestion (AD) system microorganisms under mesophilic conditions. For that, a laboratory-scale AD system was established and plastics were immersed in the sludge for a 50-day incubation period, measured for any significant mass loss. Statistical analysis showed a significant mass loss (p < 0.05) in PVC pieces with a 1.1 ± 0.16 mg average reduction, while PP and PE didn't show any significant mass loss. Raman spectroscopy analysis revealed temporally increasing novel peaks in PVC at 1729 cm
