The potential profiles of dyspnea catastrophizing and the relationship between emotion-social loneliness in elderly patients with chronic obstructive pulmonary disease.

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
ObjectiveTo explore the latent profile classification of dyspnea catastrophizing in elderly patients with chronic obstructive pulmonary disease (COPD) and its relationship with emotional-social loneliness.MethodsA total of 287 elderly patients with COPD were prospectively and consecutively recruited from five respiratory wards of the Respiratory Center at the Sixth People's Hospital of Nantong between October 2024 and April 2025. This cross-sectional study assessed dyspnea catastrophizing cognition and emotional-social loneliness using the Breathlessness Catastrophizing Scale and the emotional-social loneliness inventory. Latent profile analysis was conducted to identify potential categories of catastrophizing. Multivariate analysis of variance and generalized linear model (GLM) were used to examine the differences in emotional-social loneliness among different types of patients and the robustness of the grouping effect.ResultsThe categorization of dyspnea catastrophization can be divided into three distinct profiles: C1, the "Catastrophic-Fixation Group" (18.1%), C2, the "Vigilant-Fear Group" (50.9%), and C3, the "Adaptive-Management Group" (31.0%). These three groups of patients exhibited graded differences across each dimension of emotional-social loneliness, with C1 and > C2 >showing greater differences than C3 (
