Talvez deva tentar algumas variações de ortografia:
risk processor » risc processor (Expandir a busca), risk processo (Expandir a busca), risk process (Expandir a busca)
decrease risk » decreased risk (Expandir a busca), increase risk (Expandir a busca), decrease in (Expandir a busca)
decreased its » decreases its (Expandir a busca), decrease its (Expandir a busca), decreased with (Expandir a busca)
on decreased » in decreased (Expandir a busca), of decreased (Expandir a busca), on deceased (Expandir a busca)
its decrease » with decrease (Expandir a busca), nts decreases (Expandir a busca), to decrease (Expandir a busca)
decrease on » decrease in (Expandir a busca), decrease of (Expandir a busca), decrease or (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease NOT decrease risk processor ) OR ( decrease on decreased its decrease ))~.
