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 investigate the association of auricular plaster therapy (AP) with preoperative anxiety in patients undergoing total knee arthroplasty (TKA) and pancreaticoduodenectomy (Whipple). Methods: A prospective matched-cohort observational study was conducted at Peking Union Medical College Hospital from March 2024 to May 2025. The primary outcome was Perioperative Anxiety Scale-7 (PAS-7) scores at different preoperative timepoints. Secondary outcomes included modified Pittsburgh Sleep Quality Index (M-PSQI), satisfaction visual analog scale (VAS-satisfaction), intraoperative blood loss, postoperative VAS-pain scores, Self-Rating Anxiety Scale (SAS) scores, and incidence of delirium. Results: A total of 168 patients completed the study, and 98 patients (49 matched pairs) were included in the final analysis. The results revealed that auricular plaster (AP) therapy was significantly associated with reduced preoperative anxiety scores. Specifically, the AP exposed group demonstrated substantially lower median PAS-7 scores at both 12±2 hours before surgery (T2) and 2 hours before surgery (T3), with median differences of -4.00 points and -5.00 points, respectively (both p < 0.001). Generalized Estimating Equations further confirmed a significant group × time interaction effect (Wald χ Conclusion: In this observational study, AP was associated with reduced preoperative anxiety and improved sleep quality and may contribute to optimized postoperative recovery through its cumulative effects. Larger randomized controlled trials are needed to establish causality.
