Identification of clinical phenotypes and development of a predictive model for rapid lung function decline in COPD patients

Background Chronic obstructive pulmonary disease (COPD) exhibits significant clinical heterogeneity. This study integrates phenotype identification with longitudinal lung function analysis to develop a prediction tool for rapid decline in a large Chinese cohort. Methods This study included 38,863 COPD patients from a national multicenter screening program. Latent class analysis identified clinical phenotypes. Among 1,215 patients with baseline and 24-month follow-up spirometry, rapid decline was defined as annua…

Current reading — gain

A CatBoost model using six simple indicators screened for rapid FEV1 decline with high sensitivity and a useful negative predictive value among Chinese COPD patients with follow-up spirometry.

What this doesn’t fix

Only 1,215 of the 38,863 patients had baseline and 24-month follow-up spirometry, and the best model's AUC of 0.712 indicates moderate discrimination, so performance may not hold in broader populations.

How to verify without trusting this page

Fetch the canonical text of any version from /api/record/TRV-2026-1496 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
