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
Polyurethane foam (PUF) is the most widely used polymeric foam due to its excellent thermal insulation properties, low cost, and low density. However, its applications are limited by fire performance concerns and associated safety issues. This study describes the synthesis of a novel flame retardant and an environmentally friendly coating method aimed at enhancing the fire safety and mechanical integrity of PUF using a water-based polyethyleneimine (PEI) binder. A phosphorus/silicon-containing functionalized graphene oxide (FGO) was successfully synthesized by grafting graphene oxide (GO) with 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and 3-glycidoxypropyltrimethoxysilane (GPTMS). The chemical structure of FGO was confirmed by XPS, FTIR, and Raman spectroscopy. FGO and GO were subsequently coated onto PUF surfaces
