Talvez deva tentar algumas variações de ortografia:
fear preprocessing » fear processing (Expandir a busca), via preprocessing (Expandir a busca), image preprocessing (Expandir a busca)
decrease fear » decreased fear (Expandir a busca), decrease fetal (Expandir a busca), decreased heart (Expandir a busca)
decrease risk » decreased risk (Expandir a busca), increase risk (Expandir a busca), decrease in (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)
decrease at » decrease akt (Expandir a busca), decrease and (Expandir a busca), decrease in (Expandir a busca)
at decrease » rate decrease (Expandir a busca), that decrease (Expandir a busca), and decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease at decrease fear preprocessing ) OR ( decrease toc decrease risk decrease ))~.
