A Prediction Model for Progression of preserved ratio impaired spirometry (PRISm) Based on Longitudinal Pulmonary Function Trajectories

2026-02-17

Abstract excerpt

<title>Abstract</title> <p>Background Preserved ratio impaired spirometry (PRISm) represents a significant clinical phenotype. However, its lung function evolution exhibits marked heterogeneity, leading to substantial variability in the risk of progression to chronic obstructive pulmonary disease (COPD). This study aimed to analyze the longitudinal trajectories of lung function in patients with PRISm, identify i...
