Talvez deva tentar algumas variações de ortografia:
decrease breed » decrease need (Expandir a busca), decrease burden (Expandir a busca), decrease treg (Expandir a busca)
decrease risk » decreased risk (Expandir a busca), increase risk (Expandir a busca), decrease hiv (Expandir a busca)
risk decrease » risk decreases (Expandir a busca), risk increase (Expandir a busca), break decrease (Expandir a busca)
decrease toc » decrease of (Expandir a busca), decrease the (Expandir a busca), decreased to (Expandir a busca)
toc decrease » to decrease (Expandir a busca), the decrease (Expandir a busca), not decrease (Expandir a busca)
breed effect » field effect (Expandir a busca), fixed effect (Expandir a busca), mixed effect (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease risk decrease in decrease ) OR ( decrease toc decrease breed effect ))~.
