Randomization and Masking
A researcher who was not involved in subject enrollment generated a randomization sequence using a computer, employing a block size of 10 without stratification. The researchers responsible for subject enrollment remained blinded to the allocation sequence until the moment of allocation. Both the patients and researchers were not blinded at the time of allocation, as the intervention necessitated active participation in the mobile community. However, during follow-up visits at the outpatient clinic, the attending researchers were blinded to the group allocation. Out-of-hospital data collected through the app were automatically transmitted to the laboratory, where other researchers conducted the analysis.
