Ultrasound-guided quadratus lumborum block for postoperative analgesia in renal surgery: a systematic review and meta-analysis of randomized controlled trials.
Synthesis in Journal of anesthesia, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundQuadratus lumborum block (QLB) guided by ultrasound is a novel local block anesthesia technique, which can be used in various surgeries for multimodal analgesia. Its analgesic effectiveness for renal surgery is still uncertain. The aim of this meta-analysis was to assess the postoperative analgesic efficacy of QLB in adult patients undergoing renal surgery.
methodsWe systematically searched randomized controlled trials (RCTs) through the databases of Cochrane Library, Embase, and PubMed until June 21, 2021. Postoperative consumption of opioid in the first 24-h was set as the primary outcome. The risk of bias was evaluated by Cochrane methodology.
resultsTen RCTs involving 577 patients were eligible for our inclusion criteria. Ultrasound-guided QLB significantly reduced postoperative consumption of opioid in the first 24 h after surgery (mean differences [MD] - 17.58, 95% confidence interval [CI] - 23.14 to - 12.02, P < 0.00001, I
conclusionsUltrasound-guided QLB improves postoperative analgesic efficacy and reduces PONV in adult patients undergoing renal surgery. There is currently limited evidence concerning the analgesic effects of different QLB approaches after renal surgery, and further research is required in this area.
