Ultrasound-Guided Interscalene Brachial Plexus Block: Single Bolus Injection versus Continuous Catheter Placement in Arthroscopic Rotator Cuff Repair with Implications for Postoperative Rehabilitation - A Prospective Randomized Unblinded Trial.
Trial report in Local and regional anesthesia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Purpose: This study examined the effectiveness of the interscalene brachial plexus single-shot block (ISBSS) versus continuous block (ISBC) in managing acute and chronic postsurgical pain (PSP) in patients undergoing upper extremity surgery, and differences between the two groups in rehabilitation. Patients and Methods: Patients who underwent shoulder arthroscopy under locoregional anesthesia received either single-shot (ISBSS group) (n = 42) or continuous perineural catheter (ISBC group) anesthesia (n = 38). The primary outcome was the numeric rating scale (NRS) score related to PSP evaluation. Secondary outcomes included the American Shoulder and Elbow Surgeons Score (ASES), range of motion (ROM) in degrees, hospital length of stay, and opioid consumption, all measured postoperatively and during the rehabilitation evaluation. Results: ISBC group exhibited lower median [interquartile range, IQR] NRS score than ISBSS group at postoperative hour 20 (2 [2 to 3] vs 4 [2 to 5]), 24 (2 [2 to 2] vs 4 [1 to 5]), 48 (1 [1 to 2] vs 4 [4 to 5]), 72 (1.5 [1 to 2] vs 5 [4 to 5]) ( Conclusion: Continuous interscalene brachial plexus catheter infusion may effectively control acute and chronic PSP, facilitating better rehabilitation and healing than single shot injection.
