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
In hand surgery, postoperative rehabilitation is essential for achieving optimal functional recovery. Although continuous peripheral nerve block at the forearm level is considered a useful method for maintaining motor function while relieving pain, it has not been widely adopted due to concerns about invasiveness and the reliability of the technique. We have developed a simplified, reliable, and safe continuous peripheral nerve block technique by applying the parallel method used in conventional ultrasound-guided nerve blocks. First, hydrodissection in the axial view creates space around the target nerve, allowing for easy identification of nerves that are difficult to visualize in the sagittal view. Additionally, this space serves as a target for catheter placement, enabling the introducer needle to be advanced safely into the area surrounding the nerve in the sagittal view. We believe that this novel approach will enable more effective postoperative rehabilitation in hand surgery.
