ACPA: Anti-Citrullinated Peptides Antibodies. AV: Absolute Value. FEV 1: Forced Expiratory Volume in one second. FRC: Functional Residual Capacity. FVC: Forced Vital Capacity. IC: Inspiratory Capacity. MMEF: Maximal-Mid Expiratory Flow. RV: Residual Volume. SVC: Slow Vital Capacity. TLC: Total Lung Capacity. %: percent of predicted values. Quantitative and categorical data were mean±SD and number (%), respectively. * p-value < 0.05: 2 sided Chi-square test (comparison of categorical data between the 2 groups) Student's T test (comparison of quantitative data between the 2 groups).
