The efficacy and safety of continuous transmuscular quadratus lumborum block for postoperative analgesia after laparoscopic nephrectomy: A prospective randomized clinical trial.
Article in Journal of anaesthesiology, clinical pharmacology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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 and Aims: Analgesic efficacy and safety of continuous catheter technique in transmuscular quadratus lumborum block (QLB3) for laparoscopic nephrectomy has not been studied. This study was planned to evaluate the efficacy and safety of ultrasound (US)-guided continuous QLB3 for postoperative analgesia after laparoscopic nephrectomy. Material and Methods: In this randomized, open-label, single-centered trial, 64 patients belonging to the American Society of Anesthesiologists, physical status grade I and II, 18-65 years of age, scheduled for laparoscopic nephrectomy were included. Patients were randomized into the QLB group and the control group. After surgery, the QLB group received transmuscular QLB with a 0.4 mL/kg bolus of 0.25% ropivacaine and catheter insertion for continuous infusion of 0.25% ropivacaine at 0.1 mL/kg/h. Patients in both groups received fentanyl (0.5 μg/kg) as rescue analgesia by IV PCA pump. Results: The data of 30 patients in each group were analyzed. Total fentanyl consumption during the first 48 h postoperatively was significantly lower in the QLB group compared to the control group (mean ± SD; QLB group = 74.33 ± 32.75 μg; control group = 209.10 ± 52.04 μg) ( Conclusions: US-guided continuous catheter transmuscular QLB reduced postoperative opioid consumption by 64.45% and decreased NRS pain scores after laparoscopic nephrectomy without complications.
