“…In seven (Blair et al, 2000;Gonzales et al, 2007;Homma et al, 2003, treatment arms 1 and 2; Maki et al, 2001, treatment arm 1; Niittynen et al, 2007;Nguyen et al, 1999, treatment arm 1) out of 17 treatment arms in which the earliest LDL-cholesterol measurement was made after two weeks of the intervention, the maximum LDL-cholesterol lowering effect was already attained after 2 weeks of the intervention; in another six (Hallikainen and Uusitupa, 1999, treatment arms 1 and 2; Maki et al, 2001, treatment arm 2; Nguyen et al, 1999, treatment arms 2 and 3; Seki et al, 2003a) of these 17 treatment arms most of the reduction was already achieved after two weeks. In the four remaining studies (Matvienko et al, 2002;Deveraj et al, 2004;Saito et al, 2006;Seki et al, 2003b) it took longer than two weeks before the maximum reduction was reached.…”
