The Effect of Transmuscular Quadratus Lumborum Block on Postoperative Opioid Consumption in Patients Undergoing Percutaneous Nephrolithotomy: A Randomized Controlled Study.
Article in Cureus, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 This study aimed to investigate the effect of ultrasound-guided transmuscular quadratus lumborum block (QLB) on postoperative opioid consumption in patients undergoing percutaneous nephrolithotomy (PCNL). Methodology A total of 40 patients aged between 18 and 60 who were classified as American Society of Anesthesiologists status I-II and scheduled for unilateral PCNL were randomly divided into two groups. Patients in Group QLB (n = 20) received a single-shot QLB with 20 mL of 0.25% bupivacaine in the preoperative period. No intervention was performed in the control group (Group C, n = 20). Dermatomes affected by the block procedure were evaluated in the preoperative period in the group of patients who were administered the block procedure. General anesthesia was administered to all patients in both groups. In the postoperative period, opioid consumption, pain scores, side effects related to opioid consumption, and additional analgesic requirements were recorded. Results Opioid consumption was significantly lower in Group QLB compared to Group C at all times (p < 0.05). Postoperative visual analog scale (VAS) scores during the movement were significantly lower in Group QLB compared to Group C at all times (p < 0.05). VAS scores at rest were reported to be significantly lower in Group QLB compared to Group C, except for the eighth and twelfth hours (p < 0.05). The requirement for additional analgesic agents was significantly lower in Group QLB compared to Group C (p < 0.05). Conclusions QLB reduced postoperative opioid consumption and VAS scores by providing more effective analgesia compared to the control group in patients who underwent PCNL.
