Bilateral external oblique intercostal plane block (EOIPB) in patients undergoing laparoscopic cholecystectomy: A randomized controlled trial.
Trial report in Saudi medical journal, 2023. 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 28 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.

Abstract
objectivesTo measure tramadol intake in the first 24 hours post-surgery. In addition, pain scores and quality of recovery were evaluated as secondary outcomes.
methodsA total of 80 adult patients scheduled for laparoscopic cholecystectomy were randomized into 2 groups (with and without external oblique intercostal plane block [EOIPB]). Control group of patients received standard multimodal analgesia, EOIPB was applied on each side to patients in EOIPB group in addition to multimodal analgesia. The primary outcome was to evaluate tramadol consumption at postoperative 24 hours. Secondary outcomes were evaluating the Numeric Rating Scale (NRS) scores, postoperative Quality of Recovery score (QoR-15), sedation score, the incidence of nausea and vomiting, and antiemetic consumption.
resultsIn EOIPB group, median (Q1, Q3) tramadol consumption values for 24 hours (0 [0,50] mg) were found to be significantly lower than the control group (50 [50,100] mg) (median difference -50) (
conclusionExternal oblique intercostal plane block resulted in less postoperative tramadol consumption. However, there were no minimal clinically important differences about postoperative opioid consumption. On the other hand, compared to multimodal analgesia addition of EOIPB improved overall QoR-15 scores at postoperative 24 hours.
