Talvez deva tentar algumas variações de ortografia:
decrease observed » decay observed (Expandir a busca), case observed (Expandir a busca)
observed facts » observed effects (Expandir a busca), observed at (Expandir a busca), observed data (Expandir a busca)
decrease limb » decrease lipid (Expandir a busca), decrease liver (Expandir a busca), decrease hiv (Expandir a busca)
limb decrease » will decrease (Expandir a busca)
decrease or » decrease of (Expandir a busca), decrease on (Expandir a busca), decrease pro (Expandir a busca)
or decrease » of decrease (Expandir a busca), not decrease (Expandir a busca), to decrease (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 limb decrease or decrease ) OR ( decrease in decrease observed facts ))~.
