Talvez deva tentar algumas variações de ortografia:
decrease spacing » decrease replacing (Expandir a busca), decreases spreading (Expandir a busca), decreases weaning (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)
spacing pattern » spacing patterns (Expandir a busca), pacing pattern (Expandir a busca), stacking pattern (Expandir a busca)
decrease the » decreases the (Expandir a busca), decrease in (Expandir a busca), decrease of (Expandir a busca)
the decrease » to 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 the decrease AND decrease ) OR ( decrease burden decrease spacing pattern ))~.
