Efficacy of Unilateral External Oblique Intercostal Fascial Plane Block Versus Subcostal TAP Block in Laparoscopic Cholecystectomy: Randomized, Prospective Study.
Trial report in Surgical innovation, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 12 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.

Abstract
backgroundThis study aimed to evaluate the effectiveness of unilateral external oblique intercostal nerve block (EOIB) in laparoscopic cholecystectomy surgery. MATERIAL AND
methodsAfter ethics committee approval, ASA I-II patients aged 18-70 who would undergo laparoscopic cholecystectomy surgery were included in the study. The patients were divided into two groups, external oblique intercostal nerve block (Group EOIB) and oblique subcostal transversus abdominis plane block (Group OSTAP). After surgery, EOIB or OSTAP block was administered with 20 mL of .25% bupivacaine then routine analgesia protocol was applied with iv paracetamol, and tramadol. Visual analog scale (VAS) scores and patient-controlled analgesia (PCA) consumption were monitored 24 hours after the operation. It was administered 25 mg pethidine as a rescue analgesic to patients with VAS ≥4.
resultsThirty six patients for Group EOIB and thirty four patients for Group OSTAP were included in the study. Lower VAS scores were observed in all groups. When PCA consumption, side effects, rescue analgesia consumption, and patient satisfaction were evaluated, there was no statistically significant difference between the groups (
conclusionIt was observed that EOIB showed similar analgesic activity to the OSTAP block. EOIB may also be a part of postoperative multimodal analgesia by reducing postoperative opioid consumption in LC.
