Talvez deva tentar algumas variações de ortografia:
lesions decrease » response decrease (Expandir a busca), lesions case (Expandir a busca)
decrease lesions » disease lesions (Expandir a busca), decreased response (Expandir a busca), decrease adhesion (Expandir a busca)
decrease risk » decreased risk (Expandir a busca), increase risk (Expandir a busca), decrease hiv (Expandir a busca)
risk process » risc processor (Expandir a busca), risco processo (Expandir a busca), work process (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 NOT decrease risk process ) OR ( decrease in decrease lesions decrease ))~.
