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
This research project focused on developing flexible polyurethane foams with high biodegradability, suitable as substrates for growing vegetables or cereal sprouts. These foams incorporated acetylated tapioca starch as a filler and castor oil, and their properties were evaluated. Experiments assessed how varying concentrations of acetylated starch (0, 15, 30, 45, and 60 wt%) and castor oil (0, 10, 20, and 30 wt%) affected the foams' density, tensile properties, compression set, moisture absorption, biodegradability, and microstructure. Results indicated that increasing acetylated starch concentration led to higher density, compression set, biodegradability, and closed cell percentage, while tensile strength, elongation at break, water absorption, and mean cell diameter decreased. Most changes were significant (p < 0.05), with density, compression set, biodegradability, tensile strength, elongation at break, water absorption, and average cell diameter being 21.7 kg/m
