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)
stigma effect » stigma affect (Expandir a busca), stick effect (Expandir a busca), sticks effect (Expandir a busca)
decrease to » decreased to (Expandir a busca), decrease toc (Expandir a busca), decrease the (Expandir a busca)
decrease at » decrease akt (Expandir a busca), decrease and (Expandir a busca), decrease in (Expandir a busca)
at decrease » rate decrease (Expandir a busca), that decrease (Expandir a busca), and decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease to decrease at decrease ) OR ( decrease lesions decrease stigma effect ))~.
