Talvez deva tentar algumas variações de ortografia:
decreased risk » increased risk (Expandir a busca), decreased in (Expandir a busca)
may decreased » may decrease (Expandir a busca), has decreased (Expandir a busca), by decreased (Expandir a busca)
decrease may » decrease at (Expandir a busca), decrease by (Expandir a busca), decrease human (Expandir a busca)
risk program » rsk program (Expandir a busca), rise program (Expandir a busca), milk program (Expandir a busca)
python xcode » python code (Expandir a busca), python cuda (Expandir a busca)
xcode java » codes java (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease may decreased risk program ) OR ( python xcode java python programming ))~.
