Prophylactic Effect of Prefrontal Alternating Current Stimulation on Postoperative Sleep Disturbance in Patients Undergoing Gynecological Laparoscope: A Randomized, Double-Blind, Sham-Controlled Trial.
Trial report in CNS neuroscience & therapeutics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
aimsPostoperative sleep disturbance (PSD) is a common complication following surgical procedures. We aimed to evaluate the effect of prefrontal transcranial alternating current stimulation (tACS) in preventing PSD among patients undergoing gynecological laparoscopic surgery.
methodsA total of 176 eligible patients, aged 18-65 years, with ASA Class I to III, and scheduled for gynecological laparoscopic surgery, were randomly allocated to receive either a single 20-min session of prefrontal tACS (2 mA, 7 Hz) or sham stimulation immediately after extubation. The primary outcome was the occurrence of PSD on postoperative day (POD) 1.
resultsThe intention-to-treat analysis showed a statistically significant reduction in PSD incidence on POD 1 in the active tACS group (23.9%) compared to the sham group (43.2%), with an odds ratio of 0.41 (95% CI, 0.22-0.79; p = 0.007). Additionally, patients in the active tACS group reported significantly lower anxiety scores on POD 1 (p < 0.001), while depression scores were comparable between the groups. The active tACS group also reported significantly lower pain scores, both on PODs 1 (movement: p = 0.002; rest: p < 0.001) and 3 (movement: p = 0.028; rest: p < 0.001).
conclusionsA single session of prefrontal tACS significantly reduces the incidence of PSD on POD 1 and may offer additional benefits in reducing early postoperative anxiety and pain, with a favorable safety and tolerability profile.
