Analgesic efficacy of external oblique intercostal plane block in paediatric patients undergoing upper abdominal surgeries: A randomised controlled trial.
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
Background and Aims: The external oblique intercostal (EOI) plane block is a new interfascial plane block covering both the lateral and anterior cutaneous branches of the intercostal nerves. The literature on its use is scarce in paediatric abdominal surgeries. Methods: Forty American Society of Anesthesiologists physical status I/II patients aged between 2 months and 7 years undergoing upper abdominal surgery with unilateral subcostal incision were randomised: Group E received an ultrasound guided unilateral EOI block using 0.5 mL/kg of 0.2% ropivacaine with general anaesthesia, whereas Group C received general anaesthesia (GA) only. All patients received GA in a standardised manner. Any increase in heart rate or mean arterial pressure of more than 20% was treated with intravenous (IV) fentanyl 0.5 µg/kg. Postoperatively, tramadol 1 mg/kg IV was given as rescue analgesia if the pain score was ≥4. The study's primary outcome was to assess the intraoperative fentanyl consumption. Secondary outcomes included postoperative pain score at 1, 4, 8, 16, and 24 h at rest, time to first rescue analgesic administration, 24 h tramadol consumption, and incidence of side effects such as nausea and vomiting. Results: The mean intraoperative fentanyl consumption was lower in Group E: 12 [standard deviation (SD: 10.1] [95% confidence interval (CI): 7.3, 16.7] µg as compared to Group C: 20.5 (8.35) [95% CI: 16.7, 24.3] µg ( Conclusion: The single-shot EOI block can decrease perioperative opioid requirement and pain score. It can form an integral part of a multimodal analgesic regime for upper abdominal surgeries in paediatric patients.
