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
A novel ultrasound-assisted magnetic sorbent-wrapped stick dip extraction (UA-MSWS-DE) method was developed for the batch-scale determination of seven tyrosine kinase inhibitors (TKIs) in human plasma. The extraction device was fabricated by immobilizing octadecylphosphonic acid-functionalized magnetic nanoparticles onto flame-sealed glass capillaries embedded with magnets. Ultrasonic-assisted dip extraction was used to extract TKIs from diluted plasma, followed by quantification via liquid chromatography-tandem mass spectrometry (LC-MS/MS). Key extraction parameters were systematically optimized, yielding the following optimal conditions: sample pH 5.0 and volume 1.0 mL, sorbent particle size 20 nm and dosage 10 mg, extraction time 20 min, and desorption with 150 µL of ethanol for 8 min. The method demonstrated excellent linearity (R
