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 evaluate the effect of intravenous esketamine administration during anesthesia induction on postoperative sleep quality in female patients undergoing laparoscopic surgery. Methodology: This study was designed as a prospective, double-blind, single-center randomized controlled trial and was conducted at Huzhou Maternity & Child Health Care Hospital between December 5, 2025, and January 31, 2026. One hundred ASA I-II female patients (25-50 years) undergoing elective laparoscopic surgery (Dec 2025-Jan 2026) were randomized to control (Group C, n=50) or esketamine (Group S, n=50). Both groups received propofol 2 mg/kg, cisatracurium 0.15 mg/kg, and sufentanil 0.3 μg/kg for induction; Group-S additionally received esketamine 0.3 mg/kg, while Group-C received normal saline. Anesthesia was maintained with propofol (4-6 mg/kg/h) and remifentanil (0.1-0.2 μg/kg/min) via infusion pumps to maintain the Bispectral Index (BIS) between 40 and 60 and end-tidal carbon dioxide (PETCO Results: Ninety eight patients (Group C: 49; Group S: 49) completed the study. Group-S had lower PSQI scores on POD one and three (P<0.05), reduced intraoperative sufentanil consumption (P<0.05), lower 6/24 hours VAS scores (P<0.05), and lower 24 hours rescue analgesia rate (P<0.05). No significant differences in emergence time, PACU duration, or adverse event rates were observed (P>0.05), with no severe adverse events. Conclusion: Administration of 0.3 mg/kg esketamine during anesthesia induction reduces opioid consumption, improves early postoperative sleep quality, and decreases sleep disturbance incidence in female laparoscopic patients without increasing adverse event risks.
