Association Between Serum Growth Factors and Risk of Acute Exacerbation in Chronic Obstructive Pulmonary Disease: A One-Year Prospective 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
Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation associated with enhanced chronic airway inflammation. Growth factors implicated in COPD's inflammatory processes may serve as biomarkers for disease progression and exacerbation risk. This study evaluated the relationship between serum growth factors and COPD exacerbations over one year. Serum levels of eleven growth factors, including brain-derived neurotrophic factor (BDNF), leukemia inhibitory factor (LIF), fibroblast growth factor-2 (FGF-2), vascular endothelial growth factor (VEGF), nerve growth factor (NGF), epidermal growth factor (EGF), and stem cell factor (SCF), were measured in COPD patients at baseline. Participants were followed prospectively for one year, and associations between these biomarkers and acute exacerbations (AE) and frequent acute exacerbations (Frequent AE) were assessed using statistical analyses and receiver operating characteristic (ROC) curves. Among the study population, 42 patients experienced at least one AE within the follow-up period. Lower serum FGF-2 levels were significantly associated with increased AE risk (adjusted odds ratio significant after covariate adjustment). ROC analysis identified FGF-2 ≤ 9.12 pg/mL as a predictor of AE (AUC = 0.614, sensitivity = 64.3%, specificity = 57.1%,
