Single-Shot Versus Continuous Interscalene Block for Postoperative Pain Control After Shoulder Arthroplasty: A Prospective Randomized Clinical Trial.
Article in Journal of the American Academy of Orthopaedic Surgeons. Global research & reviews, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
introductionContinuous catheter infusion of local anesthetics extends the efficacy of regional anesthesia after prosthetic shoulder surgery. Our purpose was to compare continuous interscalene block (CIB) with single-shot interscalene block, and the hypothesis was these would offer similar safety and efficacy in patients with prosthetic shoulder arthroplasty.
methodsSeventy-six patients were randomized to ropivacaine single-shot interscalene block or CIB after prosthetic shoulder arthroplasty. Postoperative pain scores and opioid use, hospital length of stay (LOS), adverse events, and catheter tip withdrawal were recorded.
resultsPain scores (
conclusionOpioid use and pain levels during first postoperative day are clinically less after CIB, but this did not shorten LOS. The benefits of CIB may not justify the higher cost and complication rate.
