Perhaps you should try some spelling variations:
health incidence » health science, health evidence, path incidence
health incident » health including
death incidence » growth incidence, dengue incidence
nets synthesis » net synthesis, dots synthesis, its synthesis
guide network » guided network, side network, inside network
wide network » side network, mode network, fine network

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 incidence) OR (health incident))) OR (death incidence)) nets synthesis report ) OR ( health ((guide network) OR (wide network)) synthesis report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((((health incidence) or (health incident))) or (death incidence)) nets synthesis report ) or ( health ((guide network) OR (wide network)) synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (( ((((health incidence) or (health incident))) or (death incidence)) nets synthesis report ) or ( health ((guide network) OR (wide network)) synthesis report ))*.
