Table 1_Heterogeneous frailty trajectories and their differential impact on social integra

347 patients with chronic obstructive pulmonary disease (COPD) were assessed for frailty and social integration at five time points over 12 months. The data, published by Li Feng in 2026, identifies four distinct frailty development trajectories and their differential impact on social integration outcomes. The study was conducted at the Sixth People’s Hospital of Nantong City between May 2024 and January 2025.

Use Cases

• Modeling heterogeneous frailty trajectories over time based on longitudinal assessments.
• Analyzing associations between frailty progression and social network size based on the Lubben Social Network Scale.
• Investigating the relationship between frailty class and loneliness scores based on the UCLA Loneliness Scale.
• Studying the impact of clinical variables like lung function and acute exacerbations on frailty development.

Strengths

• Data includes 347 patients with complete follow-up across five time points over 12 months.
• Frailty was assessed using the validated Fried frailty phenotype.
• Social integration was evaluated across three distinct dimensions: functional, structural, and subjective experience.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is sourced from a single hospital in Nantong City, which may reflect geographic bias.
