Ultrasound-Guided Modified Clavipectoral Fascial Plane Block With Superficial Cervical Plexus Block for Midshaft Clavicular Surgery: A Prospective Randomized Controlled Trial.
Trial report in Medical science monitor : international medical journal of experimental and clinical research, 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
BACKGROUND This study evaluated the efficacy and safety of modified clavipectoral fascial plane block (mCPB) plus superficial cervical plexus block (SCPB) compared with interscalene brachial plexus block (ISBP) in midshaft clavicular fracture surgery. MATERIAL AND METHODS Fifty-six patients scheduled for midshaft clavicular surgery under regional anesthesia were randomly allocated to a control (ultrasound-guided ISBP plus SCPB) or experimental (mCPB plus SCPB) group at a 1: 1 ratio. The primary outcome was the Numerical Rating Scale (NRS) score at 12 hours postoperatively. Secondary outcomes were NRS scores at 4, 8, and 24 hours; rescue analgesic administration frequency; block success rate; procedural and onset times; and hemidiaphragmatic paralysis incidence. RESULTS Block success was 100% in both groups, without differences in performance time or onset time. A significant group × time interaction was observed (P<0.001). Compared with the control group, the experimental group had significantly lower NRS scores at 12 hours (estimated mean difference -1.29; P<0.001) and 24 hours (estimated mean difference -2.36; P<0.001). No significant differences occurred at 4 or 8 hours. Rescue analgesic requirements within 24 hours were significantly reduced in the experimental group (P=0.002). Hemidiaphragmatic paralysis incidences were 71.4% in the control group and 0% in the experimental group (P<0.001). CONCLUSIONS In midshaft clavicular fracture surgery, mCPB plus SCPB provided effective anesthesia with procedural characteristics comparable to ISBP, while avoiding hemidiaphragmatic paralysis and demonstrating superior analgesia at 12 and 24 hours. These findings require validation in larger multicenter trials.
