Effectiveness of Brachial Plexus Blocks in Obesity: Secondary Analysis of Randomized Controlled Trial.
Trial report in Hand (New York, N.Y.), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundBrachial plexus block for hand and upper extremity procedures in the obese presents a unique set of technical challenges. The authors examined how obesity affects procedural success, quality of anesthesia, and patient satisfaction.
methodsSecondary analysis of a randomized control trial comparing the retroclavicular versus supraclavicular brachial plexus block for distal upper extremity surgery was conducted. Patients were randomized to supraclavicular or retroclavicular brachial plexus block groups in the original trial. In this study, the authors dichotomized patients by obesity to compare differences in outcomes.
resultsSixteen of 117 patients (13.7%) were obese. The groups were statistically well balanced in terms of baseline and operative variables. Obese patients had increased imaging time 2.7 minutes (95% confidence interval [CI], 1.44-3.92) versus 1.9 minutes (95% CI, 1.64-2.16),
conclusionFindings from this trial suggest that despite an increased procedural difficulty, the use of both supraclavicular and retroclavicular brachial plexus blocks is associated with comparable quality of anesthesia, similar complication profile, equal opioid requirements, and similar patient satisfaction in the obese.
