Improved Sealed Venous Indwelling Needle in Ultrasound-Guided Thyroid Cyst Puncture Sclerotherapy: Characteristics and Applications.

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
Objective: To assess the safety and efficacy of an improved sealed venous indwelling needle for ultrasound-guided sclerotherapy of thyroid cysts in comparison with the standard percutaneous transhepatic cholangiography (PTC) needles. Methods: Two trapezoidal incisions (2 mm in topline, 1 mm in baseline, and 1 mm in height) were made along the needle core groove at the soft distal end of a sealed venous indwelling needle to create a novel open-window sealed venous indwelling needle. To evaluate the efficacy and safety of this improved needle, we conducted a prospective cohort study with a historical control group, comparing the improved needle with standard 21-gauge PTC needles in the treatment of 68 cystic thyroid nodules. Key outcomes included technical success, which encompasses successful needle placement, complete aspiration, and sclerosant delivery, as well as a reduction in cyst volume at the 3-month follow-up, and procedural outcomes, complications (bleeding, infection, and extravasation), procedural pain, and patient satisfaction (assessed using a 5-point Likert scale). Results: Sixty-eight cysts in 52 patients (median age, 54 years) were treated. Technical success was achieved in 94.1% (32/34) procedures versus 87.5% (28/34) in the PTC needle cohort ( Conclusion: The improved sealed venous indwelling needle provides higher technical success, greater cyst volume reduction, fewer complications, and less pain than PTC needles, offering a safer and more effective alternative for ultrasound-guided thyroid cyst sclerotherapy.
