关于OF的理解

About 70 percent had graduated from college, thought only 30 percent had graduated with honors. A few had even
dropped out, but nearly half of these had returned to graduate. Of the men, 80 percent were in one of the professions or in business management or semiprofessional jobs. The women who had remained single had office, business, or
professional occupations.

Of the men 这个怎么理解呢？翻译时怎么翻译呢？

跟后面的women形成并列平行结构……
同时鉴于楼主另外一个问题的情况，相信楼主已经有了这个句子的翻译，所以不行翻译了……
