1 · What the graph read from it

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.

2 · The registry

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

purposeHeart rate variability biofeedback (HRV-BF) is an effective psychophysiological intervention, with short-term effects of increased autonomic nervous system homeostasis, strengthened baroreflex sensitivity, and decreased hostility in patients with coronary artery disease (CAD). The study examined the 1-year HRV-BF effect on cardiovascular prognosis of these patients.

methodsOf 222 patients with CAD referred by cardiologists, 210 were screened and randomly assigned to the HRV-BF and control groups. All patients received psychophysiological assessment and completed psychological questionnaires at pre- and post-interventions and 1-year follow-up. The cardiovascular prognosis primary endpoints included hospital readmission, emergency revisits, and mortality.

resultsThe HRV-BF group had fewer all-cause readmissions (12.00 vs. 25.42%) and all-cause emergency visits (13.33 vs. 35.59%) than the control group. The low-frequency HRV in the HRV-BF group increased at post-intervention and 1-year follow-up compared with that at pre-intervention. Although no significant interaction effect was found in the standard deviation of the normal-to-normal intervals (F = 2.96, p = 0.055), it increased by 26.68% from pre- to post-intervention and 15.77% from pre-intervention to follow-up in the HRV-BF group. However, it decreased by 3.60% from pre- to post-intervention and increased by 1.99% from pre-intervention to follow-up in the control group. Depression and hostility scores decreased significantly at post-intervention and 1-year follow-up only in the HRV-BF group.

conclusionsThe long-term HRV-BF effect was confirmed by improved cardiovascular prognosis, increased cardiac autonomic homeostasis and baroreflex sensitivity, and decreased depression and hostility. HRV-BF is an effective psychophysiological intervention with short- and long-term effects in cardiac rehabilitation programs.
