For severity, intensity was recorded for 35 of 37 events, with two events (one during placebo and one during ursodeoxycholic acid treatment) having no recorded intensity. For the relationship with study treatment, 19 events were recorded as having no relationship (“none”), whilst three events during UDCA treatment had no relationship assessment recorded.
