The interrelationship between nutritional risk, psychological factors, and quality of life in chronic obstructive pulmonary disease (COPD): a hospital-based cross-sectional study.

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
backgroundA strong link exists between nutritional status, psychological factors, and quality of life in chronic diseases.
aimThis cross-sectional study aimed to evaluate the nutritional status, quality of life (QoL), and symptoms of anxiety/depression in patients with chronic obstructive pulmonary disease (COPD), and to examine the relationships among these factors.
methodsData were collected by face-to-face interviews. Anxiety and depression status were evaluated with the Hospital Anxiety and Depression Scale (HADS), and health-related QoL with the SF-12. In addition to biochemical parameters, weight and height values were obtained from patient files. Neck, calf, and mid-upper arm circumference measurements were taken. Nutritional status was screened with NRS-2002, and 24-h food records were collected. Postprandial fatigue was also questioned.
resultsThe study included 180 patients. Anxiety was observed in 37% of patients, depression in 55%; 75.6% reported experiencing postprandial fatigue. NRS scores were higher, and QoL scores were lower in those with anxiety/depression. A positive correlation was found between anxiety and depression and NRS, QoL scores, and disease duration. Postprandial fatigue was associated with all these variables, and COPD duration, number of medications, NRS, and MCS were determining factors for anxiety, while NRS, PCS, and MCS were determining factors for depression. Additionally, dietary fiber and magnesium intakes were insufficient in patients with COPD.
conclusionsThis study showed that anxiety and depression in COPD patients are closely associated with higher nutritional risk and longer disease duration and are inversely linked to QoL. This highlights the importance of providing integrated psychological and nutritional support in managing the disease.
