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: Laparoscopic liver resection (LLR) is widely performed for the treatment of liver diseases. Effective postoperative pain control is essential, particularly in patients vulnerable to opioid-related complications due to impaired hepatic function. This study compared the analgesic efficacy and recovery outcomes of ultrasound-guided erector spinae plane block (ESPB) and subcostal transversus abdominis plane block (TAPB) in patients undergoing LLR. Methods: In this single-center randomized controlled trial (ChiCTR2300078378), 120 patients scheduled for LLR were randomly allocated to receive ESPB, subcostal TAPB, or standard care (CON). The primary outcomes were postoperative pain scores at rest and during coughing. Secondary outcomes included cumulative opioid consumption, time to first patient-controlled intravenous analgesia (PCIA) activation, rescue analgesia use, and effective PCIA requests. Early recovery outcomes included time to ambulation, first flatus, length of hospital stay, Quality of Recovery-15 (QoR-15) scores, and adverse events. Results: All 120 patients were included in the analysis. Significant time-by-group interactions were observed for postoperative NRS pain scores at rest and during coughing ( Conclusion: In this single-center randomized trial, both subcostal TAPB and ESPB provide effective opioid-sparing analgesia and improve early recovery after LLR. Neither technique demonstrated consistent superiority across postoperative pain trajectories, suggesting that either block can be incorporated into multimodal analgesia strategies for LLR.
