Effect of music intervention on heart rate variability: a systematic review and meta-analysis of randomized controlled trials.

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 evaluate the effects of music intervention on heart rate variability (HRV). Methods: The protocol of this systematic review has been submitted for registration in the PROSPERO databa se, an international prospective register for sys tematic reviews, with ID number CRD420261283257. Data sources included electronic databases searched from inception through January 2026. Randomized clinical trials comparing music intervention with control were included. The primary outcomes were changes in HRV parameters after music intervention or control compared to baseline within each group. Mean differences (MD) with 95% confidence intervals (CI) were calculated for continuous variables. The methodological quality of the studies was assessed according to the Cochrane Handbook. Publication bias was evaluated using funnel plots and Egger's regression test. Results: A total of 24 randomized controlled trials involving 1,295 participants were analyzed. The meta-analysis demonstrated that music intervention significantly increased high-frequency power in normalized units (HFnu) compared to control groups (MD = 7.05, 95% CI: 1.00-13.10, Conclusion: Music intervention significantly improved LFnu and HFnu compared to control groups. People with emotional disorders can improve their HRV through music intervention. Systematic review registration: PROSPERO, Identifier: CRD420261283257.
