Article in Journal of pain research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
Background: We aimed to investigate the effects of the external oblique intercostal plane block (EOIPB) and subcostal transversus abdominis plane (TAP) block on postoperative pulmonary function in patients undergoing laparoscopic cholecystectomy. The primary outcome was spirometric pulmonary function test (PFT) results. Secondary outcomes included postoperative pain scores, opioid consumption, and postoperative recovery assessed using the Quality of Recovery (QoR)-15 questionnaire. Methods: A total of 102 patients aged 18-65 years with ASA physical status I-III who underwent elective laparoscopic cholecystectomy were included in this prospective observational study. According to the perioperative analgesia technique applied, patients were evaluated in three groups: Group Subcostal (n=34), Group EOIPB (n=34), and Group Control (n=34). After losses to follow-up, 90 patients were included in the final analysis. Preoperative and postoperative spirometric PFTs, postoperative pain scores, opioid consumption, and QoR-15 scores were recorded and compared among groups. Results: Postoperative reductions in FVC, FEV Conclusion: Both EOIPB and subcostal TAP block were associated with attenuated decline in postoperative pulmonary function, reduced opioid consumption, and improved early postoperative recovery after laparoscopic cholecystectomy.
