Ultrasound-guided double-needle lavage for acute calcific periarthritis of the hand: technical description and preliminary experience in five patients.
Article in Journal of ultrasound, 2026. 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
This study describes a standardized ultrasound-guided double-needle lavage technique for acute calcific periarthritis of the hand and reports its technical feasibility and preliminary clinical outcomes. Five consecutive patients underwent ultrasound-guided percutaneous lavage. Clinical characteristics, affected joint, calcification size, sonographic features, complications, and visual analog scale (VAS) scores at baseline, 1 week, and 1 month were recorded. Four cases involved the metacarpophalangeal joints, whereas one involved the interphalangeal joint. Mean calcification size was 14.4 ± 6.0 mm. All deposits were mature and showed no posterior acoustic shadowing. Mean VAS decreased from 8.8 ± 1.8 at baseline to 0.4 ± 0.5 at 1 week and 0.2 ± 0.4 at 1 month, corresponding to mean pain reductions of 94.2% and 96.7%, respectively. No complications occurred. Ultrasound-guided lavage appears feasible, safe, and minimally invasive, providing rapid and substantial pain relief. Larger prospective studies are needed to confirm these preliminary findings.
