a Correlation between circulating polymers and FEV1/FVC in homozygous and heterozygous Z patients. b Correlation between circulating polymers and FEV1 (%) in homozygous and heterozygous Z patients. FEV1: forced expiratory volume in the 1st second; FVC: forced vital capacity; r indicates Pearson correlation coefficient; Linear regression fit (solid line) and 95% confidence interval (dashed line) of circulating polymer concentrations compared with FEV1/FVC and FEV1 (%) values
