Ultrasound-guided semispinalis obliquus plane block for posterior upper cervical spine surgery: Technical description and case series.
Article in Indian journal of anaesthesia, 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
Posterior upper cervical spine surgeries are associated with significant postoperative pain due to extensive soft tissue and muscular dissection, leading to increased nociception transmitted via multi-segmental dorsal rami innervation. We describe the application of a novel ultrasound-guided cervical paraspinal interfascial plane [semispinalis obliquus plane (SOP)] block as a part of multimodal analgesia in ten patients undergoing occipitocervical or atlantoaxial procedures. All patients achieved adequate analgesia; 3 of 10 required minimal rescue fentanyl within the first 24 h, and no block-related complications were observed. The SOP block is a simple, safe, and potentially effective adjunct for perioperative multimodal analgesia in posterior upper cervical spine surgeries, warranting further evaluation.
