To be fair, only 22 participants in the study had both had a panorex and developed such a tumour.

公平地说，只有22名研究参与者拍过全颌X光并患有脑膜瘤。

But according to Dr Claus, the panorex was not common when most of the people in the study had been children.

但据克劳斯医生说，以前研究对象大部分是儿童，拍全颌X光的现象并不普遍。

Even more troubling was the finding that people who had been given a panorex when they were under ten had 4.9 times the normal risk of developing a meningioma.

更让人担忧的发现是十岁以下拍过全颌X光的人患脑膜瘤的概率是正常风险值的4.9倍。
