As part of this process they don't mention having gathered the medical records of the crew members. However, in 8.4 they mention they are now going to gather information on crew. Seems a bit strange they have waited so long
Sect 1.5 of the Factual Information report makes it perfectly clear that they have already gathered a great deal of information about the crew, including their medical records.
S8.4 of the Interim Statement is merely listing the various headings under which they are conducting analysis of said factual information.
