Continuous Femoral Nerve Block Versus Continuous Epidural Analgesia for Postoperative Analgesia in Knee Surgeries: A Randomized Controlled Trial.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPostoperative pain in knee surgeries hampers rehabilitation and increases morbidity. Continuous femoral nerve block (CFNB) and continuous epidural analgesia (CEA) are widely used, but their comparative efficacy remains uncertain.
objectiveThis study aimed to compare the analgesic efficacy, hemodynamic stability, and rescue analgesic requirements of CFNB and CEA in patients undergoing knee surgeries.
methodsIn this double-blind randomized controlled trial, 70 American Society of Anesthesiologists (ASA) grades I and II patients (18-60 years) undergoing elective knee surgeries were randomized into two groups. Group A received CFNB with 0.2% ropivacaine at 6 ml/hr. Group B received CEA with 0.2% ropivacaine at 6 ml/hr. Visual Analogue Scale (VAS) pain scores were recorded at 0-48 hours postoperatively. Hemodynamic parameters and rescue analgesia were also assessed.
resultsBoth groups showed comparable VAS scores throughout 48 hours (p > 0.05). At six hours, VAS was 4.06 ± 1.19 in Group A vs. 4.29 ± 0.67 in Group B (p = 0.32). Hemodynamic parameters remained stable, and rescue analgesic requirements were not significantly different.
conclusionCFNB and CEA provide equivalent postoperative analgesia and hemodynamic stability in knee surgeries. Either technique may be chosen based on patient profile and institutional preference.
