Please provide suggestions to improve your friend’s CRF.
First of all, I wold like to commend that this CRF is consist of more detail with good separation, which maybe good to get more data. However, it migh lead to take time for data collection. In part of screening, I suggest that CRF cold be added study site ID, and gender that following their study design. Moreover, size of charactor such as “dd/MMM/yyy” that have to consistant. Another part is enrollment, regrading to vaccination history which redundant information from screening visit. Although one heading of enrollment was missed, I still suggest that you well done. However, I never design CRF for vacination trial. Overall, this CRF was well done, but some point have to consider that important to add for save time or friendly use.
