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
Objective: To study the efficacy of esketamine as an adjuvant for fascia iliaca compartment block (FICB) on postoperative analgesia in elderly patients undergoing total hip arthroplasty(THA). Methodology: This study is a single-center prospective randomized controlled study. Sixty elderly patients who underwent THA at the 904th Hospital of the Joint Logistics Support Force of PLA from August 2025 to December 2025 were randomly divided into the observation group and the control group by the random number table method. The observation group conducted FICB with esketamine at concentration of 0.3 mg/kg combined with 30 mL of 0.375% ropivacaine, while the control group conducted FICB with 30 mL of 0.375% ropivacaine alone. Postoperative pain intensity, intraoperative anesthetic consumption, first press time of patient-controlled intravenous analgesia (PCIA) pump , number of effective PCIA pump presses, frequency of rescue analgesia, duration of sensory block, patient satisfaction and adverse reactions were compared between two groups. Results: The observation group showed a significantly lower VAS score both at rest and exercise T6(P<0.05), T12(P<0.05).Whether at rest or at exercise, comparison of the VAS score trends over time between two groups showed statistically significant differences(P<0.05). Intraoperative anesthetic consumption, number of effective PCIA pump presses and frequency of rescue analgesia within 48 hours after opreation were also significantly lower in the observation group (P < 0.05). Duration of sensory block and time for PCIA pump first press were significantly longer in the observation group (P < 0.05). Conclusion: Esketamine used as an adjuvant in FICB is safe and effective for elderly patient undergoing THA, providing effective pain relief, prolonging postoperative analgesia duration, with few adverse reactions and high patient satisfaction.
