Characterization and Application of Calotropis Procera Fiber as a Sustainable Filter for Oil Removal from Aqueous Emulsion.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Fibers extracted from Calotropis procera (CP) fruits were successfully used to filter engine oil from a synthetic oil-in-water effluent. Fiber morphology was examined by scanning electron (SEM) and optical (OM) microscopies, while their structural, vibrational and chemical properties were systematically studied by thermogravimetric analysis (TG), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy. It was first demonstrated that the fibers are tubular with strong anisotropy and that when placed in oil, most oil adsorption occurs at their internal surfaces, a region with higher hemicellulose concentration. Contact angle experiments and standard gravimetric measurements confirmed that the fibers are hydrophobic, while FTIR results have suggested a small amount of water retained within the fiber walls after forced submersion. Using a cylindrical filter in continuous mode and a semispherical filter in batch mode, the percentile of oil removal (OR %) was 67% for 200 mg of fiber mass (FM) and a flow rate (Q) of 172 mL min
