In COHERE we have asked the cohorts to indicate what has been the source of information for coding the causes of death. We identified 5 possible options: 1) Did not apply any method, just had the codes mapped into HICDEP/CoDe 2) Applied full Cause of Death (CoDe) protocol within own cohort 3) Used data received back from the ART-CC 4) Used data received back from DAD 5) A mixture of the above. If the answer was “5) A mixture of the above”, we asked the cohorts to verify for each patient, submitted to COHERE in 2013, whether the source of information for the coding of causes of death was: A=Code method within own cohort B=Data from ART-CC C=Data from DAD X=Other - please specify Therefore we introduced a variable == source == in the table LTFU. Could we introduce this variable also in HICDEP? See also the WP4 minutes of 11 June 2013.
