Five patients in cohort 3 were not available for FibroScan ® analysis (3 placebo and 2 active) because of unavailability of the instrument at the site (1 placebo and 1 active), unavailability of the appropriate instrument probe (1 active), a technically inadequate baseline scan (1 placebo), and the Day 63 scan not being performed (1 placebo). |
