Does Ultrasound-Guided Quadratus Lumborum Block Improve Pain after Hysterectomy.

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
Objective: Determine whether the quadratus lumborum block (QLB) is an effective adjunct to control postoperative pain during the first 24 hours after minimally invasive hysterectomy. Methods: Prospective cohort observational study of patients who underwent laparoscopic or robotic hysterectomy. Patients either received a QLB or did not. Initial postoperative pain scores were recorded in the postanesthesia recovery area using a numeric rating scale. Patients were then called to collect 24-hour scores and analgesic medication usage. The primary outcome was the 3-hour pain score. Secondary analysis evaluated use of analgesic medication. Results: Fifty patients were enrolled in the study: 25 patients in the no-QLB cohort and 25 patients in the QLB group. The median postoperative pain scores (out of 10) were 4, 2, and 6 at 1, 3, and 24 hours in the no-QLB group. Scores were 5 ( Conclusion: There was no significant pain difference between the no-QLB and QLB groups. Patients who received a QLB were more likely to receive pain medication 3 hours after surgery. Thus, the use of a QLB does not appear to be a suitable adjunct for postoperative pain.
