The effects of equi-efficacious doses of the cholesterol-lowering drugs simvastatin (20 mg day-1) and pravastatin (40 mg day-1) on tests of cognitive function were investigated in a double-blind, placebo-controlled, 2-period (4 weeks per period), incomplete block, crossover study of 36 patients (24 per treatment) with hypercholesterolaemia. After 4 weeks neither of the active treatments differed significantly from placebo on any cognitive measure.
在一项双盲、安慰剂对照、两阶段(每个阶段4周)、不完全区组、交叉研究中,对36例高胆固醇血症患者(每种治疗24例),研究了等效剂量的降胆固醇药物辛伐他汀(20毫克/天)和普伐他汀(40毫克/天)对认知功能测试的影响。4周后,在任何认知指标上,两种活性治疗与安慰剂相比均无显著差异。
