被动语态的过去分词后面为何没by

尊敬的老师好，这里的reported后面没by，请问是漏掉了还是一个英语里的使用方法

Thus kids who watch television and play video games instead of being active are setting themselves up for a sedentary future, reported a recent Harvard University Medical School Special Health Report.

reported a recent Harvard University Medical School Special Health Report.

这并非被动语态，而是引述分句，主语和谓语动词倒装了。像下句：

They were still waiting, said Tom.

引语做了主句，引述分句以插入语的形式出现。这种结构称为自由间接引语。
