Talvez deva tentar algumas variações de ortografia:
their decrease » the decrease (Expandir a busca), their disease (Expandir a busca), the decreased (Expandir a busca)
increase their » increase the (Expandir a busca), increases the (Expandir a busca), increased the (Expandir a busca)
decrease the » decreases the (Expandir a busca)
the subjects » the subject (Expandir a busca), the subjective (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)
of decrease » or decrease (Expandir a busca), not decrease (Expandir a busca), to decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease in decrease of decrease ) OR ( increase their decrease the subjects ))~.
