Hemidiaphragmatic paralysis after costoclavicular approach versus other brachial plexus blocks in upper limb surgery: a meta-analysis.
Synthesis in Korean journal of anesthesiology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
backgroundThe costoclavicular brachial plexus block (CCB) is a recently established technique that uses the infraclavicular approach and is performed just below the clavicle. This meta-analysis aimed to determine whether CCB can reduce the incidence of hemidiaphragmatic paralysis (HDP), which is a major adverse event related to brachial plexus block (BPB), while yielding comparable block performance as other BPB techniques.
methodsWe searched electronic databases to identify relevant studies that compared the incidence of HDP between CCB and other BPB techniques. The primary outcome was the incidence of HDP following CCB and other BPB techniques. The secondary outcomes were pulmonary function test results, other adverse events, and block performance parameters such as onset and performance time.
resultsWe included six randomized controlled trials that included 414 patients. Compared with the other BPB group, the CCB group had a significantly lower incidence of HDP (relative ratio: 0.21, 95% CI [0.12, 0.36], P < 0.001) and higher peak expiratory flow rate (mean difference: 0.68 L/s, 95% CI [0.13, 1.23], P = 0.015). There were no significant between-group differences with respect to other adverse events and block performance parameters.
conclusionsCompared with other BPB techniques, CCB involves a lower incidence of HDP with comparable onset and performance time.
