Perhaps you should try some spelling variations:
"cadth optimal use report" » "path optimal use report", "width optimal use report", "health optimal use report", "cadth optimal time report", "cadth optimal use reports", "cadth optimal user report", "cadth optimal lse report"
"CADTH optimal user portal" » "CADTH optimal upper portal", "CADTH optimal fused portal", "CADTH optimal laser portal", "CADTH optimal user port", "CADTH optimal user portrait", "CADTH optimal liver portal", "CADTH optimal timer portal"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("CADTH optimal user portal") OR ("cadth optimal use report")).
• Removing quotes may allow a broader search: (( CADTH optimal user portal ) or ( cadth optimal use report )).
• Adding a wildcard symbol may retrieve word variants: (("CADTH optimal user portal") or ("cadth optimal use report"))*.
