Hi Saurabh,
This is a review-specific check on top of CDISC compliance. Age is a common Inclusion criteria in study Protocols. Sponsor needs to confirm that a subject screening process was executed correctly.
For Screen Failures a Age calculation algorithm is usually different compare to randomized subjects. For example, date of Screening Visit may be used instead of date of Randomization or the first Dose of study drug.
Kind Regards,
