NCIt definition : The relative timing for a performed activity expressed as the number of days offset
from the study-defined reference activity (e.g. date of registration, start of treatment).
(BRIDG);
Alternative definition : BRIDG 3.0.3: The relative timing for a performed activity expressed as the number
of days offset from the study-defined reference activity (e.g. date of registration,
start of treatment) for this particular subject. EXAMPLE(S): Day 1, Days 10-20; OTHER
NAME(S): Study Day; NOTE(S): Derived from the dateRange of this activity minus the
dateRange of the reference activity 1. The study-defined reference activity can
be different from study to study. The study day for a date after this reference activity
is a positive integer calculated as the difference in the two dates 1. The study
day for dates before the reference activity is a negative integer calculated as the
difference between the two dates. Note that this means there is no Day 0.; BRIDG 5.3: The relative timing for a performed activity expressed as the number of
days offset from the study-defined reference activity (e.g., date of registration,
start of treatment) for this particular experimental unit. EXAMPLE(S): Day 1, Days
10-20 OTHER NAME(S): Study Day NOTE(S): Derived from the dateRange of this activity
minus the dateRange of the reference activity 1. The study-defined reference activity
can be different from study to study. The study day for a date after this reference
activity is a positive integer calculated as the difference in the two dates 1.
The study day for dates before the reference activity is a negative integer calculated
as the difference between the two dates. Note that this means there is no Day 0.;
