Fig. 3From: Association between circulating alpha-1 antitrypsin polymers and lung and liver diseasea Correlation between circulating polymers and LSM in homozygous and heterozygous Z patients. b Correlation between circulating polymers and ELF test in homozygous and heterozygous Z patients. LSM: liver stiffness measurements; r indicates Pearson correlation coefficient; Linear regression fit (solid line) and 95% confidence interval (dashed line) of polymer concentrations compared with LSM and ELF testsBack to article page
