The 95% Effective Duration of Music for Anxiolysis Before Elective Cesarean Delivery.
Trial report in A&A practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06969105 (A Randomized Controlled Trial of Music Use in Parturients Admitted to Labor & Delivery), which is not on this 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.

Abstract
backgroundMusic can be used in the perioperative period as a nonpharmacological intervention to reduce anxiety, but how long it should be played to be effective is unknown. The goal of this study was to determine the 95% effective duration (ED95) of music of different subtypes for anxiolysis in parturients awaiting elective cesarean delivery. It was hypothesized that the overall ED95 would be <15 minutes and similar between music groups.
methodsA prospective, randomized, biased coin study was conducted at a major academic institution. Consented parturients undergoing elective cesarean delivery were randomly assigned to one of 2 music groups: preselected Mozart sonatas or patient preference. Music duration began at 4 minutes and was subsequently increased, decreased, or kept the same based on the previous subject's response. Anxiety on a verbal scale of 0 to 10 and vital signs were compared pre-and postmusic. Successful intervention was defined as a decrease in anxiety by at least 1 point. Primary ED95 estimates with centered isotonic regressions (CIRs) were compared utilizing 83% confidence intervals (CI), while turning-point and simple means were compared with Student's t tests for sensitivity analysis.
resultsA total of 57 pregnant women were approached and 40 agreed to participate. The mean age was 33 (standard deviation [SD] 5.1). Primary ED95 estimates by CIR were 6.8 (83% CI, 5.9-8.4) minutes and 6.7 (83% CI, 5.9-8.3) minutes for Mozart and personal preference music, respectively. Mean ED95 by CIR for any music type was 6.8 minutes. Mean immediate postintervention anxiety reduction with Mozart music was 1.7 (SD 1.4) and personal preference was 2.6 (SD 2.0). There were no significant changes in heart rate or blood pressure immediately after music.
conclusionsPlaying music for <7 minutes is a versatile, effective, and low-risk method for anxiolysis in women awaiting elective cesarean delivery.
