  • It is perfectly true, as philosophers say, that
    life must be understood backwards. But they
    forget the other proposition, that it must be
    lived forwards.
  • Søren Kierkegaard

5
Starting with the output and working backwards
  • Two questions could occur to us
  • How is Time to Event Calculated
  • What is a Dermatological Event

6
The Figure 14.1 is Listed in the Analysis Results
Level Metadata
7
From the Analysis Level Metadata we can get to
the SAP and the Supporting Dataset ADTTE
The Analysis Results Level Metadata also links to
the Analysis Dataset Level Metadata
The Analysis Results Level Metadata links to a
written description of Time to Event and
Dermatological Event appears in the SAP
8
Use of Dataset and Variable Level Metadata
Analysis Dataset Level Metadata has the Analysis
Variable Level Metadata and links to the
computational method for Time to event
COMP_ADTTE_TTP
and also links to the source dataset, ADAE
9
Use of Dataset and Variable Level Metadata
The ADAE Analysis Dataset Level Metadata has the
Analysis Variable Level Metadata for
Dermatological Event, AEDERMFN and links to the
appropriate computational method,
COMP_ADAE_AEDERMFN
10
Use of Dataset and Variable Level Metadata ? to
the CRF
From AEDECOD we can go to the SDTM AE and its
Variable Level Metadata
AEDECOD Variable Level Metadata links to the
Annotated CRF
