Talvez deva tentar algumas variações de ortografia:
risk decreases » diet decreases (Expandir a busca), life decreases (Expandir a busca), oic decreases (Expandir a busca)
decrease risk » decreased risk (Expandir a busca), increase risk (Expandir a busca), decrease in (Expandir a busca)
decreases bim » decreases in (Expandir a busca), decreases hip (Expandir a busca), decreases il (Expandir a busca)
decrease to » decreased to (Expandir a busca), decrease toc (Expandir a busca), decrease the (Expandir a busca)
bim objects » in objects (Expandir a busca), belt objects (Expandir a busca), from objects (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 ( decrease risk decreases bim objects ))~.
