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
Postoperative pain is a common consequence of spinal operations related to tissue trauma, manipulation of neural structures, and lengthy procedures. While opioid medications are frequently used for pain control, their side effects, such as nausea, vomiting, tolerance, and dependency, have led to increased interest in multimodal analgesic techniques. This review aims to examine effectiveness and safety of liposomal bupivacaine (LB, EXPAREL) in erector spinae plane blocks (ESPB) for postoperative pain management following spinal surgery. Regional anesthesia methods, particularly ESPB, have gained attention in reducing opioid requirements. The ESPB technique involves ultrasound-guided administration of local anesthetics beneath the erector spinae muscles and above the transverse process, effectively inhibiting ventral and dorsal rami of spinal nerves. Despite its popularity for versatility and safety, the analgesic effects of ESPB with conventional local anesthetics are relatively short-lived. LB, which releases the drug gradually as liposomes are degraded, offers extended pain control. Early clinical applications in pediatric scoliosis surgery and transforaminal lumbar interbody fusion have revealed that ESPB with LB adequately outperformed the control analgesic in terms of opioid consumption (30% and 50% decrease in mentioned studies) and length of stay (24%, 32%, and 12% decrease in mentioned studies). These findings indicate that LB in ESPB represents a promising strategy for enhanced perioperative pain management in spinal procedures. However, further research with larger and more diverse patient populations and outcome measurements are needed to overcome the current limitations of current research. In the present investigation, current evidence regarding the implementation of LB in ESPB during spine surgeries is summarized, focusing on safety and potential to improve patient outcomes by prolonging analgesia, minimizing opioid use, and promoting faster recovery.
