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
Purpose: Ultrasound-guided quadratus lumborum plus modified erector spinae plane (QLESP) block and pericapsular nerve group (PENG) plus lateral femoral cutaneous nerve (LFC) block are novel regional analgesia techniques for total hip arthroplasty (THA). This retrospective study aimed to compare the analgesic efficacy and opioid-related outcomes of the QLESP block and the PENG + LFC block following THA. Methods: This retrospective study included 2180 patients who underwent THA between January 2022 and December 2024. In this study, 272 patients received the QLESP block (QLESP group) and 420 patients accepted the PENG + LFC block (PELF group). Propensity score matching (PSM) was performed to match patients in a 1:1 ratio. Results: Of 2180 patients identified, 256 pairs between QLESP group and PELF group were successfully matched. In the match cohort, the QLESP group demonstrated significantly lower cumulative sufentanil consumption (QLESP: 13.0 ± 1.3 μg; PELF: 14.6 ± 3.3 μg; Conclusion: This observational study suggested that the QLESP block was associated with a modest reduction in early postoperative sufentanil consumption, PCIA frequency at 6 hours, and postoperative length of stay for total hip arthroplasty, compared to PENG + LFC block. Given the inherent limitations of the retrospective PSM design, the routine incorporation of these blocks into enhanced recovery pathways for total hip arthroplasty in clinical practice warrants further large randomized controlled trials.
