Randomization
BLIND
A third‐party statistician used SPSS 18.0 (SPSS Inc., USA) to generate a random number table, which was used by the specialist nurses to assign the participants to the online (multidisciplinary collaborative management) and conventional (conventional management) groups. Each group was further divided into subgroups of 10 participants, according to the order of enrolment.Although the participants were told they were divided into two groups when signing the informed consent form, the investigators did not tell the grouping of the participants, and the participants were not informed of the exact content of the management plan. They were simply told what they needed to know. This blinding method was approved by the ethics committee. All investigators and personnel involved in data collection and evaluation were blind to grouping. All personnel involved in data entry, monitoring and analysis were blind to grouping until data lock.
