Talvez deva tentar algumas variações de ortografia:
decreased risk » increased risk (Expandir a busca), decreased in (Expandir a busca)
risk decrease » risk decreases (Expandir a busca), risk increase (Expandir a busca), break decrease (Expandir a busca)
decrease belt » decrease cell (Expandir a busca), decrease akt (Expandir a busca), decrease at (Expandir a busca)
decrease to » decreased to (Expandir a busca), decrease toc (Expandir a busca), decrease the (Expandir a busca)
objects » object (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease OR decrease to decrease ) OR ( decreased risk decrease belt objects ))~.
