Liposomal bupivacaine for popliteal sciatic and saphenous nerve blocks in patients undergoing foot and ankle surgery: a single-center, double-blind, randomized controlled trial.
Trial report in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Patients undergoing foot and ankle surgery often experience severe postoperative pain. This study aimed to assess the efficacy of liposomal bupivacaine for popliteal sciatic and saphenous nerve blocks in managing pain after foot and ankle surgery. Methods: The study was registered with the Chinese Clinical Trial Registry (ChiCTR2400088305) and received ethical approval from the Institutional Review Board of Xuzhou Renci Hospital (XZRCLL-KT-202407003). In this randomized trial, 142 patients undergoing elective foot/ankle surgery received popliteal-sciatic and saphenous nerve blocks with either 50 mg ropivacaine (R group) or 133 mg liposomal bupivacaine (L group). Primary outcome was postoperative sufentanil consumption; secondary outcomes included analgesia duration, motor blockade, recovery quality, sleep quality, and adverse events. Results: Compared with Group R, Group L demonstrated significantly lower sufentanil consumption at 12 h, 24 h, 48 h, and 72 h postoperatively (all Conclusion: The administration of liposomal bupivacaine for popliteal sciatic and saphenous nerve blocks significantly reduces postoperative opioid consumption and extends nerve block duration, providing a safe and effective technique for postoperative analgesia in patients undergoing foot and ankle surgery. Preoperative sleep quality, surgical type, and Pain Catastrophizing Scale score are independent predictors of the pain trajectory that can identify patients more likely to benefit from liposomal bupivacaine.
