Safety and efficacy of the external oblique intercostal plane block for postoperative analgesia in upper abdominal surgery: A systematic review and meta-analysis.
Review in Saudi journal of anaesthesia. 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
The external oblique intercostal block (EOIB) is a novel regional anesthesia technique for upper abdominal surgery. However, its efficacy and safety compared to other analgesic strategies remain uncertain. This study aimed to evaluate the impact of EOIB on postoperative analgesia and recovery in adults undergoing upper abdominal surgery. PubMed, Web of Science, and the Cochrane Library were searched from inception until August 2025 for randomized controlled trials comparing EOIB to placebo, no block, or other regional techniques. Primary outcomes were 24-h postoperative opioid consumption and pain scores (rest/movement). Secondary outcomes included rescue analgesia requirement, opioid-related adverse effects, block-related complications, and recovery parameters. EOIB significantly reduced postoperative opioid consumption when compared with control at 24 h (SMD - 0.45;
