Regional block anesthesia for adult patients with inguinal hernia repair: A systematic review.
Synthesis in Medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07527065 (Comparison of the Postoperative Analgesic Efficacy of Ultrasound-Guided TAP Block and Quadratus Lumborum Block in Spinal Anaesthesia for Open Inguinal Hernia Repair), which is not on this map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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.

Abstract
backgroundInguinal hernia repair (IHR) is a common surgical technique performed under regional block anesthesia (RBA). Although previous clinical trials have explored the effectiveness and safety of RBA for IHR, no systematic review has investigated its effectiveness and safety in adult patients with IHR.
methodsThis systematic review searched electronic databases (PubMed, Embase, Cochrane Library, CNKI, Wangfang, and VIP) from their inception to July 1, 2022. We included all potential randomized controlled trials that focused on the effects and safety of RBA in adult patients with IHR. Outcomes included operative time, total rescue analgesics, numerical rating scale at 24 hours, occurrence rate of nausea and vomiting, and occurrence rate of urinary retention (ORUCR).
resultsFive randomized controlled trials, involving 347 patients with IHR, were included in this study. Meta-analysis results showed that no significant differences were identified on operative time (MD = -0.20; fixed 95% confidence interval [CI], -3.87, 3.47; P = .92; I² = 0%), total rescue analgesics (MD = -8.90; fixed 95% CI, -20.36, 2.56; P = .13; I² = 28%), and occurrence rate of nausea and vomiting (MD = 0.39; fixed 95% CI, 0.13, 1.16; P = .09; I² = 0%) between 2 types of anesthesias. However, significant differences were detected in the numerical rating scale at 24 hours (MD = -1.53; random 95% CI, -2.35, -0.71; P < .001; I² = 75%) and ORUCR (MD = 0.20; fixed 95% CI, 0.05, 0.80; P = .02; I² = 0%) between the 2 management groups.
conclusionThe results of this study demonstrated that IHR patients with RBA benefit more from post-surgery pain relief at 24h and a decrease in the ORUCR than those with CSA.
