The postoperative analgesic efficacy of three peripheral nerve blocks in hip fracture surgery: a systematic review and meta-analysis of randomised trials.

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
introductionAnaesthesia for hip fracture surgery is often supplemented with a peripheral nerve block (PNB) to reduce postoperative pain. Common PNBs include fascia-iliaca compartment block (FICB) and femoral nerve block (FNB). Since the introduction of the pericapsular nerve group (PENG) block, debate continues as to which technique provides superior analgesia. This review aimed to compare the postoperative analgesic efficacy of three PNBs when administered perioperatively to adult hip fracture patients.
methodsCINAHL, Cochrane CENTRAL, Embase, Medline, Web of Science and Google Scholar were searched in April 2025. Statistical analysis was performed using a random-effects model.
results19 randomised trials (1059 patients) were included. Pain scores between PENG and FICB at 6, 12 and 24 h were not significantly different. Compared to FNB, PENG significantly lowered pain scores at 6 h (P = 0.004). Opioid consumption in the 24 h postoperative period was significantly lower in PENG than FICB (P = 0.02), but not in FNB. No outcome reached the minimal clinically important difference. Evidence was graded very low to moderate.
conclusionThere is insufficient evidence to state superiority of PENG over FICB or FNB when used perioperatively in patients undergoing hip fracture repair. No included studies reported time to mobilisation, highlighting a significant evidence gap in existing primary research. Further high-quality, sufficiently powered randomised trials are still needed.
