Top relative risk statistics and P-values reflect tests for whether patients in one treatment group were more likely to experience sessions associated with IDHEs which were treated by reducing the UF rate only (IDHE category 1). Bottom statistics reflect tests for whether patients in one treatment group were more likely to experience sessions associated with IDHEs which were treated with saline (IDHE categories 2a & 2b).
