Talvez deva tentar algumas variações de ortografia:
decrease making » decrease walking (Expandir a busca), decrease during (Expandir a busca), decrease owing (Expandir a busca)
decreased their » decrease their (Expandir a busca), decreased the (Expandir a busca), decreasing their (Expandir a busca)
their decrease » the decrease (Expandir a busca), their disease (Expandir a busca), the decreased (Expandir a busca)
and decreased » and decreases (Expandir a busca), and increased (Expandir a busca)
decrease and » decreases and (Expandir a busca), decrease in (Expandir a busca), decrease of (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease and decreased their decrease ) OR ( decrease OR decrease making process ))~.
