Effects of erector spinae plane block and quadratus lumborum block on postoperative opioid consumption in laparoscopic prostatectomy: a randomized controlled clinical trial.

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
backgroundThe quadratus lumborum block (QLB) and erector spinae (ESP) block are relatively new, regional analgesic techniques adapted to abdominal surgery to reduce opioid consumption in the postoperative period. The aim of this study was to compare the effectiveness of the ultrasound-guided bilateral ESP block and the bilateral QLB for patients undergoing laparoscopic radical prostatectomy (LRP).
methodsAdult patients who underwent LRP were randomly allocated to one of two equal groups. Group I received an ultrasound-guided ESP block with 30 mL of 0.35% ropivacaine on both right and left sides. Group II received an ultrasound-guided QLB1 with 30 mL of 0.35% ropivacaine on both right and left sides.
resultsThere were 104 included patients, 52 patients in the ESP block group and 52 in the QLB group. There was no statistically significant difference in oxycodone consumption within the first 24 hours after surgery between the groups (P = 0.115, 95% CI, for ESP group 17.32-27.56, and for QLB group 22.04-31.07). Pain was evaluated using Numeric Rating Scale (NRS) at 1, 2, 6, 12, and 24 hours after surgery, with no significant differences between the groups (P = 0.325).
conclusionsBoth bilateral QLB and ESP block provided effective postoperative analgesia in patients undergoing LRP. No statistically significant differences were observed between groups in terms of opioid consumption and pain scores during the first 24 hours. However, this trial was not designed or powered to establish equivalence or non-inferiority, and therefore such conclusions cannot be drawn.
