Talvez deva tentar algumas variações de ortografia:
decrease lesions » disease lesions (Expandir a busca), decreased response (Expandir a busca), decrease adhesion (Expandir a busca)
lesions decrease » response decrease (Expandir a busca), lesions case (Expandir a busca)
decrease risk » decreased risk (Expandir a busca), increase risk (Expandir a busca), decrease hiv (Expandir a busca)
decrease and » decreases and (Expandir a busca), decrease of (Expandir a busca), decrease the (Expandir a busca)
and decrease » and decreases (Expandir a busca), and decreased (Expandir a busca), and increase (Expandir a busca)
risk objects » risk subjects (Expandir a busca), disk object (Expandir a busca), first objects (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease and decrease lesions decrease ) OR ( decrease in decrease risk objects ))~.
