1 · What the graph read from it

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

backgroundThe external oblique intercostal plane (EOIP) block is a novel technique proposed for upper abdominal analgesia; however, its clinical efficacy remains unclear. This study compares EOIP and subcostal TAP (sTAP) blocks in laparoscopic cholecystectomy (LC), focusing on postoperative pain scores and opioid requirements.

methodsEighty patients were divided into two groups: EOIP block and subcostal TAP. Bilateral blocks were performed with 20 ml 0.375% bupivacaine in both groups after general anesthesia. Patients were evaluated in the PACU and postoperative periods. Visual analogue pain scores (VAS) and opioid consumption were measured.

resultsThere was no statistical difference between VAS scores at rest and active movement at all measurement times (p > 0.05). Opioid consumption in the first 4 h was less in the sTAP group than in the EOIP group (p = 0.039) However, there was no statistical difference in opioid consumption at 24 h (p = 0.215). There was no statistical difference between the groups in terms of rescue analgesia, opioid and block-related complications (p > 0.05).

conclusionsGiven its comparable efficacy to the subcostal TAP block in lessening opioid consumption and postoperative pain, the EOIP block represents a practical and effective adjunct to multimodal analgesia procedures in LC. TRIAL REGISTRATION NUMBER: NCT05632991 (registered at clinicaltrials, principal investigator: Ali Ahiskalioglu, registration date: November 21, 2022).
