- Patients with antibody levels above and below cut-off, with and without deterioration in forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), total lung capacity (TLC), the diffusing capacity for carbon monoxide (DLCO) measured by a single breath (DLCO-SB), and DLCO/VA within 3 years, p values (log-rank test) as well as number of analyzed patients are shown
- Hazard ratios derived from the Cox proportional hazards model highlight the relationship between deterioration in lung function parameters and anti-CXCR3/anti-CXCR4 antibody levels
