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
Shoulder arthroscopy has become a common procedure, but it is often associated with severe postoperative pain. This study aims to evaluate the analgesic effect of ultrasound-guided coracoid approach brachial plexus block combined with posterior suprascapular nerve block in shoulder arthroscopy. To this end, fifty patients undergoing right shoulder arthroscopy were randomly divided into two groups with 25 patients in each group. Before induction of general anesthesia, patients in the two groups received different nerve blocks. In Group A, participants received ultrasound-guided supraclavicular brachial plexus block with 25 mL 0.3% ropivacaine. In Group B, coracoid approach brachial plexus block and posterior suprascapular nerve block were carried out under ultrasound guidance. M-mode ultrasound was used to measure diaphragm movement before and 30 min after the block, and the presence of hemidiaphragm paralysis was recorded during calm breathing and deep breathing. Pain scores were recorded at 1, 6, 12, 24 and 48 h after surgery. The actual press times of the PCA pump and consumption of sufentanil were also recorded.A total of 45 patients completed this study. The incidence of hemidiaphragm paralysis in Group B was significantly lower than that in Group A under both calm breathing and deep breathing. The two groups displayed similar pain scores at 1, 6, 12, 24 and 48 h after surgery. Compared with supraclavicular brachial plexus block, coracoid approach brachial plexus block combined with posterior suprascapular nerve block can significantly reduce the occurrence of hemidiaphragm paralysis with an equivalent postoperative analgesic effect for shoulder arthroscopy. Therefore, the latter may be beneficial for early postoperative recovery in patients who cannot tolerate hemidiaphragm paralysis.
