Of 5,033 patients examined between 1968 and 1975, 407 were diagnosed as having psoriasis (Ps) and 23 alopecia areata (Aa). Five of the 23 patients with Aa had also Ps. One Aa patient having pitting of the nail only was not included in the Ps group. One further patient with Aa himself not affected with Ps had a sibling with Ps. It is suggested that there is an association between Ps and Aa and that the pitting of the nails described in Aa may be in reality an expression of Ps.
在1968年至1975年间接受检查的5033名患者中，407人被诊断患有银屑病（Ps），23人患有斑秃（Aa）。23名斑秃患者中有5人也患有银屑病。仅指甲有凹痕的1名斑秃患者未被纳入银屑病组。另有1名未患银屑病的斑秃患者有1名患银屑病的兄弟姐妹。提示银屑病与斑秃之间存在关联，且斑秃中描述的指甲凹痕可能实际上是银屑病的一种表现。
