NOTES: The lower limit of detection varied among subjects depending on the assay used at the specific clinical research site; RNA values below the limit of detection were replaced with the lower limit of the assay (e.g., 18 cp/mL was replaced with 50 cp/mL for an assay with the limit of detection of 50 cp/mL).
