Evaluation of the analgesic efficacy of ultrasound-guided quadratus lumborum block for laparoscopic renal surgery: a randomized controlled trial.
Trial report in BMC anesthesiology, 2025. 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
purposeTo evaluate the analgesic efficacy of ultrasound-guided quadratus lumborum block (QLB) for laparoscopic renal surgery.
methodsSixty-eight patients who underwent unilateral laparoscopic renal surgery were enrolled. All patients were separated into two groups: group QLB (n = 34) and group C (n = 34). Patients in the QLB group underwent unilateral anterior QLB before the induction of anesthesia. Patients in group C underwent laparoscopic renal surgery with no block. Postoperative NRS scores at rest and during movement at 6, 12, 24, 48 h were assessed. Remedial analgesia and the incidence of adverse reactions within 48 h after surgery were recorded. The quality of recovery was compared at 24 and 48 h after the operation via the postoperative quality recovery scale.
resultsAt 6, 12, 24 h postoperatively, the QLB group had lower resting and moving NRS scores than did the C group (P < 0.05). The QLB group had lower numbers of PCAs, remedial analgesia and incidences of nausea and vomiting within 48 h (P < 0.05). The time to first walk and exhaust was shorter in the QLB group (P < 0.05). The recovery rates of nociceptive and emotional factors at 24, 48 h in the QLB group were greater (P < 0.05). The recovery rates of the activities of daily living (ADL) factors at 24 h in the QLB group were greater (P < 0.05).
conclusionsQLBs are more effective at alleviating pain in patients undergoing laparoscopic renal surgery, which is beneficial for reducing the use of opioids, alleviating adverse reactions, improving the quality of recovery.
