Procedures of data management
A specialized team consisting of a statistician and neurologist will be responsible for data collection to ensure the confidentiality of information through electronic monitoring. This is done to ensure standardization of the study methods. The database was closely monitored for missing and redundant data. Logical checks and numerical range verifications were conducted automatically and manually. The data management processes include data entry, data submission, query generation, query replies by the corresponding researcher, feedback, and query resolution.
