Modified approach to external oblique intercostal block: a proof-of-concept pilot case series and anatomical evaluation -a case series.
Article in Korean journal of anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundRegional anesthesia techniques that provide analgesia to the entire lateral abdomen are limited. We present a modified external oblique intercostal block for complete lateral abdominal analgesia with a single injection. CASE: We performed a modified version of the external oblique intercostal block unilaterally at the tenth rib along the mid-axillary line in three patients undergoing robot-assisted partial nephrectomy (two single injections, one catheter placement) and tested the technique on a cadaver with 20 ml of dye bilaterally. All patients reported good postoperative pain relief without complications and had consistent sensory coverage of the T8-T12 dermatomes from the anterior-to-posterior axillary line. Anatomical assessment confirmed consistent bilateral staining of the lateral cutaneous branches T8-T12.
conclusionsConclusions: The initial clinical success and anatomical findings of the modified approach to the external oblique intercostal block suggest that this technique may be an effective option for lateral abdominal analgesia.
