Transversus abdominis plane block vs quadratus lumborum block for postoperative analgesia in inguinal hernia repair: A systematic review and meta-analysis.
Synthesis in Langenbeck's archives of surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeThe present review was designed to differentiate between the analgesic value of transversus abdominis plane block (TAP) vs the quadratus lumborum block (QLB) for patients undergoing inguinal hernia surgery.
methodsPubMed, CENTRAL, Scopus, Embase, Google Scholar, Open gray, and a clinical trial registry were searched up to 18
resultsSix RCTs from India, Turkey, and Norway published between the years 2019 to 2023 were included. Anesthetic agents and dosages were similar for TAP and QLB groups in each study. On meta-analysis, pain scores were not statistically significant different between TAP and QLB at 3-6 h (MD: 0.46 95% CI: -0.11, 1.03 I
conclusionLow to moderate-quality preliminary evidence suggests no difference in the analgesic efficacy of TAP and QLB for adult patients undergoing inguinal hernia repair. While there was a tendency for lower postoperative analgesic consumption with QLB, it needs to be verified by future studies.
