total preprocessing » textual preprocessing (Expandir a busca), data preprocessing (Expandir a busca), novel preprocessing (Expandir a busca)
decrease during » increase during (Expandir a busca), increases during (Expandir a busca), increased during (Expandir a busca)

decreased high » decreased in (Expandir a busca), decreased risk (Expandir a busca), decreased health (Expandir a busca)
decrease total » decreased total (Expandir a busca), increase total (Expandir a busca), decrease fetal (Expandir a busca)
high decrease » with decrease (Expandir a busca), with decreased (Expandir a busca), high increases (Expandir a busca)
