Talvez deva tentar algumas variações de ortografia:
decrease adhesion » increases adhesion (Expandir a busca), decrease asian (Expandir a busca), decreases aggression (Expandir a busca)
adhesion decrease » adhesin decreases (Expandir a busca), lesions decrease (Expandir a busca), abortion decrease (Expandir a busca)
decrease burden » disease burden (Expandir a busca), decrease further (Expandir a busca)
burden decrease » burden disease (Expandir a busca), urea decrease (Expandir a busca), burgers decreases (Expandir a busca)
decrease risk » decreased risk (Expandir a busca), increase risk (Expandir a busca), decrease in (Expandir a busca)
risk objects » risk subjects (Expandir a busca), disk object (Expandir a busca), first objects (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease _ decrease adhesion decrease ) OR ( decrease burden decrease risk objects ))~.
