Preoperative Transcutaneous Electrical Acupoint Stimulation Alleviates Postoperative Pain and Improves Sleep Quality in Breast Cancer Patients with Preoperative Sleep Disturbance: A Partially Randomized Controlled Trial.
Trial report in Journal of pain research, 2026. 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
Purpose: Preoperative sleep disturbance exacerbates postoperative pain and delays recovery. Transcutaneous electrical acupoint stimulation (TEAS) may alleviate insomnia and pain. This trial evaluated preoperative TEAS on postoperative pain, sleep, and intraoperative hemodynamics in breast cancer patients with preoperative sleep disturbance. Patients and Methods: Fifty-nine breast cancer patients (aged 37-70 years) were stratified by Pittsburgh Sleep Quality Index (PSQI): PSQI < 6 were assigned to the non-randomized control group (Group C, n = 26), while patients with PSQI ≥ 6 were randomly allocated (1:1) to the sleep disturbance group (Group S, n = 16) or the TEAS group (Group T, n = 17). TEAS (2/100 Hz, 8-12 mA, 30 min) was delivered pre-anesthesia at LI4, HT7, and PC6. Pain was assessed via Numerical Rating Scale (NRS) at 4, 24, 48, and 72 h postoperatively. Sleep was measured with Athens Insomnia Scale (AIS). Intraoperative systolic blood pressure variability (sdSBP, cvSBP) was recorded. Results: In observational comparisons, Group S exhibited elevated NRS scores at 24, 48, and 72 h vs Group C ( Conclusion: Preoperative TEAS significantly attenuates postoperative pain and improves sleep in breast cancer patients with preoperative sleep disturbance, possibly associated with reduced intraoperative blood pressure variability. Preoperative sleep quality may predict postoperative outcomes.
