Synergistic effects of polyvinylpyrrolidone and graphene oxide in thin film nanocomposite membranes for oily wastewater treatment via forward osmosis process.

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
Wastewater from the oil and gas industry is notoriously challenging to treat due to its complex composition. In this work, polyvinylpyrrolidone (PVP) was used to modify graphene oxide (GO) nanoparticles for the synthesis of PSf based thin-film nanocomposite (TFN) membranes through the interfacial polymerization (IP) technique, aimed at oil removal from wastewater. The composite membrane, incorporated with GO, at different PVP loadings (0.025 wt%, 0.030 wt%, and 0.035 wt%) were fabricated and characterized using FESEM, AFM, ATR-FTIR, UV-Vis spectra, tensile strength and contact angle goniometer. It is found that with the presence of PVP-GO inside the TFN membranes, it exhibited higher surface hydrophilicity due to an increment in hydroxyl and carboxyl groups in the polyamide (PA) layer, which improves the attraction between water molecules and membrane surface. TFN membrane assimilated with 0.035 wt% PVP-GO achieved 48.871 L/m
