On the paper form for CoDe it is asked that the person give an indication of how certain the diagnosis is. This is writen as follows:

Certainty of Diagnosis:
Definite = 95-100% certainty,
Likely = 80-95% certainty,
Possible = 50-80% certainty

I propose adding optional fields in the tblLTFU that can capture this information, for those cohorts that have it.

suggested name: Death_RDC1, DEATH_RDC2 etc for as many DEATH_Rxx there may be
(the DC should signify "Diagnosis Certainty" - since there is already a string of variables for Causality (immidiate/underlying/contributing) named DEATH_RCxx)
