Lateral quadratus lumborum block versus transversus abdominis plane block for perioperative analgesia in patients undergoing laparoscopic colorectal cancer surgery: 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
backgroundLateral quadratus lumborum block (QLB) and transversus abdominis plane block (TAPB) have been widely used in abdominal surgeries. This study aimed to compare the intraoperative analgesic effect, hemodynamic changes and postoperative complications of the two blocks in patients undergoing laparoscopic colorectal cancer surgery.
methodsThis was a randomized controlled trial that enrolled 189 patients scheduled for laparoscopic colorectal cancer surgery. Patients were randomly allocated into three groups: the QL group (n = 63) received bilateral ultrasound-guided lateral QLB; the TAP group (n = 63) received bilateral ultrasound-guided TAP block; and the GA group (n = 63) received no blocks. The primary outcome was cumulative remifentanil administration during laparoscopic colorectal cancer surgeries. Secondary outcomes included intraoperative hemodynamics (mean arterial pressure and heart rate), postoperative pain intensity, length of hospital stay and postoperative complications.
resultsOne hundred eighty-four patients were eventually enrolled in the study. Intraoperative remifentanil administration was significantly lower in the QL group (398.69 ± 169.07 µg) than the TAP group (477.25 ± 156.55 µg) and the GA group (493.25 ± 195.32 µg) (P < 0.05), and there was no significant difference between the TAP group and the GA group (P > 0.05). At pneumoperitoneum establishment and abdominal incision time point, the MAP values of the GA group (98.59 ± 14.18 mmHg and 87.57 ± 12.03 mmHg, respectively) were significantly higher than in the TAP group and the QL group (91.18 ± 15.61 mmHg; 92.30 ± 11.91 mmHg and 80.95 ± 12.06 mmHg; 82.49 ± 10.99 mmHg, respectively) (P < 0.05). VAS scores at 15 min and 6 h after surgery were significantly lower in the QL group and the TAP group than in the GA group (P < 0.05).
conclusionsIn patients undergoing laparoscopic colorectal cancer surgery, the lateral QL block was superior than the TAP block in reducing intraoperative remifentanil usage. However, both blocks could provide greater intraoperative hemodynamic stability and better perioperative analgesia.
