Comparison of two peripheral regional analgesic techniques for primary elective total hip arthroplasty: a randomised clinical trial.
Trial report in Anaesthesia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionSeveral regional anaesthesia techniques have been used in the peri-operative pain management of patients who undergo primary elective total hip arthroplasty. The erector spinae plane, pericapsular nerve group and lateral femoral cutaneous nerve blocks offer motor-sparing analgesia of the hip region but target different areas. We designed this study to compare the pericapsular nerve group block combined with lateral femoral cutaneous nerve block with the erector spinae plane block in terms of postoperative analgesia and motor impairment.
methodsOur study involved patients undergoing primary elective unilateral total hip arthroplasty. All patients received spinal anaesthesia and standardised peri-operative multimodal analgesia. Patients were assigned at random to either pericapsular nerve group and lateral femoral cutaneous nerve blocks ('anterior' block group) or erector spinae plane block ('posterior' block group). The primary outcome was intravenous morphine consumption within the first 24 h postoperatively. Secondary outcomes included: pain scores; assessment of sensory and motor block; incidence of complications; and incidence of chronic postsurgical pain.
resultsSixty-two patients completed the study. The study groups were comparable in baseline characteristics. There was no difference in morphine consumption at 24 h between patients allocated to the anterior and posterior block groups (median (IQR [range]) 5 (1-10 [0-22]) mg vs. 5 (2-8.5 [0-20]) mg, respectively; p > 0.99). Incidence of motor block was 1/31 for patients allocated to the anterior block group compared with 5/31 for those allocated to the posterior block group (p = 0.09). There were no differences in any of the secondary outcome measures between groups. DISCUSSION: We found no statistically or clinically relevant difference between two motor-sparing peripheral regional analgesic techniques among patients undergoing primary elective total hip arthroplasty with multimodal analgesia. Appropriate choice of block may be situation-dependent, and physicians should consider patient and system factors when selecting a technique.
