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
backgroundEffective pain management following hip arthroplasty is critical for patient recovery. As a key component of multimodal analgesia strategies, nerve blocks are widely utilized for postoperative analgesia. However, the comparative efficacy of different nerve block techniques remains unclear. This study employs a Bayesian network meta-analysis (NMA) to compare analgesic outcomes among six commonly used nerve block techniques after hip arthroplasty.
methodsRandomized controlled trials (RCTs) comparing postoperative pain outcomes among six nerve block techniques-supra-inguinal fascia iliaca block (FIB), erector spinae plane block (ESPB), quadratus lumborum block (QLB), pericapsular nerve group block (PENG), lumbar plexus block (LPB), and circum-psoas block (CPB)-after hip arthroplasty were systematically searched in PubMed, Embase, Web of Science, and the Cochrane Library from inception to October 15, 2024. 15 RCTs involving 1,068 patients were included. Methodological quality and evidence certainty were assessed using Cochrane RoB 2.0 and GRADE framework. A Bayesian NMA with random/fixed-effects models integrated direct and indirect evidence. Interventions were ranked using the surface under the cumulative ranking curve (SUCRA). Outcomes included static/dynamic pain scores at 12 and 24 h, 24-h intravenous morphine consumption, and postoperative adverse effects (nausea, vomiting, and dizziness).Data were analyzed using R 4.4.1 and Stata 15.
results15 RCTs (n = 1068) comparing six nerve block techniques were included. The NMA showed no statistically significant differences in static or dynamic pain scores at 12 or 24 h. For 24-h morphine consumption, CPB was associated with significantly lower use compared to QLB and FIB. Statistically significant differences were found for postoperative adverse effects. SUCRA rankings consistently indicated CPB had the highest probability of being among the most effective options across outcomes, followed by PENG. The overall certainty of evidence was moderate.
conclusionsThis NMA found no significant differences in analgesia among six nerve blocks after hip arthroplasty, but SUCRA rankings suggest CPB may be optimal for analgesia, morphine-sparing and postoperative adverse effects, while PENG may serve as an alternative in selected clinical contexts.
