Quadratus Lumborum Block Reduces Postoperative Pain Scores and Opioids Consumption in Total Hip Arthroplasty: A Meta-Analysis.
Review in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Quadratus lumborum block (QL) is a relatively new regional anesthesia technique that has been used in different surgeries for improved outcomes. There are few case reports and studies about its role in total hip arthroplasty with variable effects. This study aimed to evaluate the effect of QL block on postoperative pain control, opioid consumption, and the incidence of postoperative adverse events in total hip arthroplasty surgeries. A systematic review of the scientific literature addressing the use of QL block in hip arthroplasty was performed following the PRISMA guidelines and using the online database databases, Medline and Science Direct. We registered this review with the PROSPERO database in May 2021 (reference number-CRD42021247055). Two authors performed the literature searches in June 2021 and repeated them in July 2021 to ensure accuracy. Review Manager software (RevMan for Mac, version 5.4; Cochrane Collaboration, Oxford, United Kingdom) was used to perform a meta-analysis of studies included in our review. Five randomized controlled trials were identified for inclusion (n=394) in our meta-analysis. The results demonstrated a beneficial effect of QL block in pain control at 6, 12, and 24 hours postoperatively after hip arthroplasty (p <0.05). Opioid consumption for 24 hours was significantly reduced in the QL group (p=0.010). Our study also demonstrated that QL block is associated with a significant reduction in postoperative nausea and vomiting (PONV) (p=0.04). In conclusion, QL block can provide significantly better pain control after total hip arthroplasty at 6, 12, and 24 hours postoperatively. It also results in significantly reduced 24 hour-opioid consumption. This block is also associated with a lesser incidence of PONV and a better satisfaction level postoperatively.
