Communality indices for rates of elongation of diaphyses of short bones of the hand were computed from serial data for children with Down syndrome, 7 to 14 years of age. Communalities were larger for adjacent than for nonadjacent bones and also larger for bones grouped in rows rather than rays of the hand. This pattern is similar to that reported for normal children. Communality indices for rates of diaphyseal elongation for girls with Down syndrome were lower than those of boys with Down syndrome and normal children.
根据7至14岁唐氏综合征患儿的连续数据，计算了手部短骨干骺端伸长率的共同度指数。相邻骨骼的共同度指数高于非相邻骨骼，手部按行分组的骨骼的共同度指数也高于按射线分组的骨骼。这种模式与正常儿童的情况相似。唐氏综合征女童骨干骺端伸长率的共同度指数低于唐氏综合征男童和正常儿童。
