Clinical outcomes
4D UGET led to a significantly higher CPR when compared with the CTT group (per protocol 50% vs 36%, p = 0.02, ITT 47% vs 36%, p = 0.04). The 4D UGET group also had a higher LBR and BPR compared with the CTT group (per protocol 41% vs 28%, p = 0.02, ITT 39% vs 28%, p = 0.04 and per protocol 59% vs 46%, p = 0.02, ITT 57% vs 45%, p = 0.04 respectively) (Table Clinical outcome measures, Intention to treat (ITT) and per protocol analysis CTT versus 4D UGET.
