Twenty-five volunteers, all in their fifth decade or beyond, all with mild to moderate, nonpsychotic depression of at least several months' duration participated in a double-blind study of Gerovital vs placebo. There was no significant difference between the Gerovital and placebo groups; both groups showed significant improvement on self-rating as well as observer rating scales.
25名志愿者，年龄均在50岁及以上，均患有持续至少数月的轻度至中度非精神病性抑郁症，参与了一项关于Gerovital与安慰剂的双盲研究。Gerovital组与安慰剂组之间没有显著差异；两组在自评量表和观察者评定量表上均显示出显著改善。
