Statistics show there are 6.5 billion smartphone users globally in 2022. That means approximately 83% of the world’s population has a smartphone. If researchers leverage these and other wearable devices for BYOD eCOA data collection, it makes the process simpler, smoother, and more cost-effective. Historically, equivalency presented a primary hurdle in the adoption of eCOA BYOD for clinical trials. In recent years, studies conducted on BYOD show that equivalency does exist across the administration modes.
