Effects of external oblique intercostal plane block on postoperative pain and analgesic requirement in laparoscopic cholecystectomy: a prospective randomized controlled trial.
Trial report in BMC anesthesiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06712498 (INVESTIGATION OF THE INTRAOPERATIVE AND POSTOPERATIVE EFFECTS), which is not on this 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.

Abstract
backgroundLaparoscopic cholecystectomy (LC) is one of the most commonly performed minimally invasive surgical procedures. Postoperative pain may negatively affect patient satisfaction and recovery. External oblique intercostal plane block (EOIB) is proposed as a new regional anaesthesia technique to reduce this pain. The aim of this study was to investigate the effect of ultrasound-guided EOIB on postoperative pain scores, postoperative opioid consumption, intraoperative hemodynamic parameters, and patient satisfaction in patients undergoing LC.
methodsAfter approval of the ethics committee, 64 patients aged 18-65 years, in ASA I-II class, who underwent elective LC for cholelithiasis were included in the study. Patients were randomly allocated into two groups: the EOIB group and the control group. Visual analogue scale (VAS), heart rate, systolic-diastolic-mean arterial pressure, analgesic consumption, nausea-vomiting frequency and patient satisfaction parameters were recorded for 24 h postoperatively.
resultsVAS scores were significantly lower in favour of EOIB at all time points (p < 0.001). There was a significant difference over time and between groups. (p < 0.001) In addition, patient satisfaction was significantly higher in the EOIB group at 24 h (p < 0.001).
conclusionsEOIB improves pain control after LC, reduces the need for analgesics and significantly improves patient satisfaction.
