AWRANGE
Analysis Window Valid Relative Range
Char
Perm
The range of values that are valid for a given analysis timepoint (a given value of AVISIT). For example, "5-9 DAYS".
AWTARGET
Analysis Window Target
Num
Perm
The target or most desired analysis relative day (ADY) value or analysis relative time (ARELTM) value for a given value of AVISIT.
AWTDIFF
Analysis Window Diff from Target
Num
Perm
Absolute difference between ADY or ARELTM and AWTARGET. It will be necessary to adjust for the fact that there is no Day 0 in the event that ADY and AWTARGET are not of the same sign.
If the sign of the difference is important, then AWTDIFF might have to be used in conjunction with ADY or ARELTM and possibly AWTARGET when choosing among records.
AWLO
Analysis Window Beginning Timepoint
Num
Perm
The value of the beginning timepoint (inclusive) needs to be used in conjunction to AWRANGE. For example, if AWRANGE is "5-9 DAYS", then AWLO is "5".
AWHI
Analysis Window Ending Timepoint
Num
Perm
The value of the ending timepoint (inclusive) needs to be used in conjunction to AWRANGE. For example, if AWRANGE is "5-9 DAYS", then AWHI is "9".
AWU
Analysis Window Unit
Char
Perm
Unit used for AWTARGET, AWTDIFF, AWLO and AWHI. Examples: DAYS, HOURS.
