Perhaps you should try some spelling variations:
network synthesis » network systems
substance network » distance network, substrate network, resistance network
evidence network » science network, guidance network, dence network
sequence network » sequence networks, science network, sequential network
health evidence » health science
health sequence » health sequelae, heart sequence, health consequence

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: (((( health evidence network synthesis report ) OR ( health sequence network synthesis report ))) OR ( health substance network synthesis report )).
• Adding a wildcard symbol may retrieve word variants: (((( health evidence network synthesis report ) or ( health sequence network synthesis report ))) or ( health substance network synthesis report ))*.
