1 · What the graph read from 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.

2 · The registry

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

backgroundClavicular brachial plexus blocks are a popular method to provide analgesia in upper limb surgery. Two common approaches include the infraclavicular (IC) and supraclavicular (SC) blocks. These two techniques have been compared previously; however, it is still being determined from the current literature whether one should be favoured.

methodsA search was performed on the following databases: Ovid Medline, EMBASE and the Web of Science from inception until 30.04.2023. All RCTs comparing SC and IC approaches in upper limb orthopaedic surgery were included. The primary outcome was block success rate.

resultsEighteen RCTs comprising 1389 patients were included. The success rate of IC blocks was higher than SC blocks, odds ratio 0.61 (95% CI 0.41-0.91, p = 0.01). A small number of studies reported on secondary outcomes. A reduced rate of Horner's syndrome was observed in the IC group. Otherwise, no difference was noted between the approaches in terms of procedure time, sensory onset time, patient satisfaction, pain and vascular puncture.

conclusionIC blocks demonstrate a higher success rate over SC blocks. Across all studies a large variance in outcome reporting and definitions was observed. Future studies should conform to an agreed definition set to facilitate comparison.
