Independent predictors of quality of life in patients with chronic heart failure.

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
introductionObjective measurement of Health-Related Quality of Life (HRQoL) has proven useful in evaluating the effectiveness of medical management and its potential as a predictor of mortality and rehospitalization in patients with heart failure (HF). The aim of this study is to characterize HRQoL and determine its independent predictors in patients with chronic HF from a heart failure and transplant clinic in Colombia.
methodsThis was an analytical cross-sectional study. The outcome variable was HRQoL measured using The Minnesota Living with Heart Failure Questionnaire (MLHFQ). Descriptive analysis of sociodemographic and clinical characteristics was conducted. Simple and multiple linear regressions were performed to establish predictors, considering statistical significance at p < 0.05.
resultsA total of 200 patients were analyzed. 20% had Chagasic etiology. The median left ventricular ejection fraction (LVEF) was 30% (range 10 - 68%). The mean HRQoL score was 38.71 points (SD ± 22.67 points). "Multivariate analysis identified seven independent predictors of worse HRQoL: age (β=0.17), low vs. high socioeconomic status (β=13.45), HF etiology, Chagas vs. others (β=12.97), number of hospitalizations in the last year (β=2.94), Charlson index (β=3.47), digitalis use (β=7.34), and NYHA functional class III-IV vs. I-II (β=28.04). Angiotensin-converting enzyme use was associated with better HRQoL (β=-4.80).
conclusionThis study shows that HRQoL in chronic HF is significantly determined by a set of socioeconomic, clinical, and management factors. The identification of these predictors underpins the need for comprehensive and personalized care strategies to improve the quality of life of these patients.
