Ultrasound-guided erector spinae plane block versus anterior quadratus lumborum block for postoperative analgesia after percutaneous nephrolithotomy: A randomized controlled study.
Article in Saudi journal of anaesthesia. 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
Background: Percutaneous nephrolithotomy (PCNL) is associated with significant postoperative pain. Ultrasound-guided erector spinae plane block (ESPB) and anterior quadratus lumborum block (QLB) are increasingly used for analgesia; however, direct comparative evidence in PCNL remains limited. This randomized controlled study compared their analgesic efficacy following unilateral PCNL. Methods: Eighty-four adult patients (American Society of Anaesthesiologists I-III) were randomized to receive ESPB or anterior QLB. Three patients in each group had block failure. The primary outcome was time to first rescue analgesia. Secondary outcomes included Numeric Rating Scale (NRS) pain scores at rest and during movement at 1, 2, 6, 12, and 24 h, total tramadol consumption, complications, time to ambulation, and length of hospital stay. Results: Time to first rescue analgesia was significantly longer in Group E compared to Group Q (406.15 ± 161.97 min vs. 326.15 ± 155.61 min; mean difference 80 min; 95% CI 9-151; Conclusion: Both ESPB and anterior QLB provide effective postoperative analgesia after PCNL. ESPB offers moderate effect size prolongation in time to first rescue analgesia, suggesting a modest early postoperative analgesic advantage without increased complications.
