Blinding (masking)
ADVERSE EVENT, BLIND
The outpatient doctors (S.W.K. and L.S.M) will conduct the initial assessment of the patients from the outpatient department, enter the collected information independently, and compare the information to find errors and correct them in time. The treating physicians (Z.H.W. and Z.N.W.) are blinded to the initial evaluations and group assignments. In addition to counting and analyzing the data independently of the multiple physicians administering the intervention, the statistical analysis team will be blind to the group assignments and the purpose of the study. Unmasking occurred upon completion of the trial or the occurrence of a serious adverse event.
