Association of heart rate variability index with depressive symptoms and lung function in chronic obstructive pulmonary disease.
Article in World journal of psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundDepression is a common comorbidity in patients with chronic obstructive pulmonary disease (COPD). Research indicates that COPD affects cardiac autonomic control, and heart rate variability (HRV) serves as a simple, non-invasive measure of autonomic nerve activity. However, the relationship between HRV and lung function, as well as the impact of depressive symptoms, remains unclear.
aimTo investigate the correlation between HRV indicators and depressive symptoms and lung function in patients with COPD.
methodsA retrospective cross-sectional study involving 120 COPD patients hospitalized from January 2018 to January 2024 at our institution was conducted. Demographic and clinical characteristics were collected, and depressive symptoms were assessed using the Beck Depression Inventory (BDI). Patients were categorized into a depressed group (BDI ≥ 16) and a non-depressed group (BDI < 16). A control group consisting of 60 healthy volunteers who underwent check-ups at the same institution was also included. Statistical analyses were performed using SPSS 26.0 software. Pearson correlation coefficients were calculated to determine and compare the relationships between HRV parameters, lung function measures, and depressive symptoms across the groups.
resultsOf the 120 patients with COPD, 35.8% (43/120) were diagnosed with depression, compared to 5.0% (3/60) in the control group. The HRV index in COPD patients was significantly lower than that in the control group (
conclusionCompared to patients without COPD, the incidence of depressive symptoms is higher among patients with COPD and is negatively correlated with the patients' HRV indices. In contrast, HRV indices are positively correlated with the patients' pulmonary function parameters. Patients and healthcare professionals should enhance their awareness of depression, actively conduct depression assessment screenings, and incorporate HRV indices into disease management. This approach aims to improve the psychological health of patients and ultimately enhance their prognosis and quality of life.
