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
Electrospun nanofibers of polyacrylonitrile/Ni-metal-organic framework 74 (PAN/Ni-MOF-74) were prepared and utilized as a novel sorbent for spin-column micro-solid-phase extraction (SC-μSPE) of atenolol (ATN) and captopril (CAP). The electrospun nanofibers were characterized by field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction analysis. Ni-MOF-74 nanoparticles in the polymeric network of polyacrylonitrile considerably enhance the extraction efficiency of the electrospun sorbent due to providing hydrophobic, hydrogen bonding, and π-π interactions with the target analytes. The entire procedure, including sample loading, washing, and eluting of the target analytes was performed by centrifugation of the spin column. The extracted analytes were then quantified by high-performance liquid chromatography with a diode array detector. Various parameters affecting extraction efficiency were optimized using the one-variable-at-a-time method. Under optimum conditions, the calibration plots were linear in the range 0.5-500 ng mL
