A modified hip pericapsular nerve block on postoperative pain and functional outcome after total hip arthroplasty: a prospective, double-blind, randomized controlled study.
Trial report in Korean journal of anesthesiology, 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
backgroundThis study aimed to explore the efficacy and safety of the hip pericapsular nerve block (hip-PNB), which combines the anterior pericapsular nerve group (PENG) and posterior pericapsular deep-gluteal (PPD) blocks, on postoperative pain and functional outcomes after total hip arthroplasty (THA) via the posterolateral approach.
methodsSeventy patients undergoing THA were allocated to either the nerve block group (Group N, hip-PNB + sham local infiltration analgesia [LIA]) or the control group (Group C, sham hip-PNB + LIA). The primary outcome was cumulative morphine consumption in the first 24 h postoperatively. Secondary outcomes included visual analog scale pain scores at rest and during movement postoperatively, time to first rescue analgesia, cumulative morphine consumption during hospitalization, opioid consumption during surgery, postoperative recovery, and postoperative complications.
resultsCompared with Group C, Group N consumed significantly less morphine in the first 24 h (10 [0, 10] mg vs. 10 [10, 20] mg; P < 0.001) and throughout hospitalization (10 [0, 20] mg vs. 20 [20, 30] mg; P < 0.001) and had less opioid consumption perioperatively. Group N also had significantly lower pain scores at rest and during movement in the first 24 h, required rescue analgesia later, and had faster recovery postoperatively than Group C. No significant intergroup differences were observed in quadriceps muscle strength or postoperative complication rates.
conclusionsCompared to LIA, hip-PNB has better postoperative analgesia and enhances recovery in patients undergoing THA.
