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
Background: Effective postoperative analgesia is essential after hip surgery to facilitate early mobilization and reduce opioid consumption. The fascia iliaca compartment block (FICB) is commonly used for perioperative analgesia, with both suprainguinal and infrainguinal approaches described; however, their relative efficacy remains uncertain. This systematic review and meta-analysis compared the analgesic effectiveness of suprainguinal versus infrainguinal FICB in hip surgery. Methods: A systematic search of PubMed, Scopus, Web of Science, and Google Scholar was conducted from inception to the final search date. Randomized or prospective comparative studies involving adult patients undergoing hip surgery and directly comparing suprainguinal with infrainguinal FICB were included. Primary outcomes were time to first rescue analgesia and postoperative opioid consumption. Secondary outcomes included pain scores and adverse events. Data were pooled using random-effects models, and risk of bias was assessed using the Cochrane Risk of Bias 2 tool. Results: Seven studies comprising 660 patients met the inclusion criteria. Suprainguinal FICB significantly prolonged time to first rescue analgesia compared with the infrainguinal approach (mean difference 121.40 minutes; 95% CI 4.60-238.19), with substantial heterogeneity. Postoperative opioid consumption was significantly lower with suprainguinal FICB (standardized mean difference -1.35; 95% CI -2.29 to -0.41). Pain scores generally favored the suprainguinal approach, particularly between 6 and 24 hours postoperatively. No major block-related complications were reported, and adverse event rates were comparable. Conclusion: Suprainguinal FICB provides superior postoperative analgesia and reduces opioid requirements compared with the infrainguinal approach in patients undergoing hip surgery, supporting its preferential use within multimodal analgesia strategies.
