  1. Intra-assay reproducibility was measured by 3 sequential measurements of IPF% in the same sample, with *indicating the mean of these 3 results. The inter-assay reproducibility was measured by repeating the IPF% in the same patient after 12 months, with **indicating the mean of these 2 results. Total represents the mean and SD of six patients.
