Experiment flowchart. FAS=number of people randomly enrolled−number of people who did not use any research equipment; PPS=FAS lost to follow-up or the patient withdraws from the study; SS=FAS−number without any safety assessment (lost to follow-up). FAS, full analysis set, PPS, per-protocol set, SS, safety analysis set.
