Talvez deva tentar algumas variações de ortografia:
decrease regressive » decrease aggressive (Expandir a busca), decrease depression (Expandir a busca), increase aggressive (Expandir a busca)
regressive effect » suppressive effect (Expandir a busca), progressive effort (Expandir a busca), expressive effects (Expandir a busca)
decrease akt » decrease at (Expandir a busca), decrease after (Expandir a busca), decrease with (Expandir a busca)

decrease and » decreases and (Expandir a busca), decrease in (Expandir a busca), decrease of (Expandir a busca)
