Trial report in Medical science monitor : international medical journal of experimental and clinical research, 2026. 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
BACKGROUND Postoperative sleep disturbances are common after gynecological laparoscopic surgery, possibly delaying recovery. This study evaluated whether additional postoperative administration of dexmedetomidine hydrochloride nasal spray could improve anxiety, sleep quality, and early recovery in patients who routinely received preoperative dexmedetomidine hydrochloride nasal spray. MATERIAL AND METHODS In this prospective, single-blind, randomized, controlled, single-center study, 80 patients undergoing elective gynecological laparoscopic surgery were enrolled from June 2024 to December 2024 and randomized to a control group (n=40) or dexmedetomidine group (n=40). Both groups received 50 μg dexmedetomidine hydrochloride nasal spray 30 minutes before anesthesia. The dexmedetomidine group received an additional 75 μg at 9: 30 PM on the night of surgery. Anxiety was assessed using the Hamilton Anxiety Scale (HAMA). Sleep was evaluated using the Athens Insomnia Scale (AIS) and sleep wristbands. RESULTS Baseline characteristics, postoperative pain, and postoperative nausea and vomiting were comparable between groups (all P>0.05). Both groups showed significantly decreased HAMA scores after preoperative medication compared with baseline (both P<0.001). Compared with controls, the dexmedetomidine group showed no significant difference in total AIS score on the night of surgery (P=0.771), but had a higher proportion of patients without subjective sleep deterioration (25.0% vs 5.0%, P=0.012), longer total sleep time (P=0.030), higher proportion of deep sleep (P=0.040), fewer awakenings (P=0.020), and shorter postoperative hospital stay (P<0.001). CONCLUSIONS Additional dexmedetomidine hydrochloride nasal spray on the night after surgery improved objective sleep structure and reduced subjective sleep deterioration without increasing adverse reactions.
