肖氏弧的一个疑问：纽约大学做过临床试验吗？

这篇文章说做过一个40人的。怎么找不到任何报告呢？

The National Institutes of Health sponsored a trial for 40 spinal-cord-injured patients at New York University in 2003.

可是这篇报道说纽约大学只做了两例：

But Xiao says 110 spinal cord injury patients and 230 with spina bifida have undergone the procedure, including two at New York University where he began the research years ago. He has reported a fraction of those cases in respected urology journals, suggesting about 80 percent resume voiding eventually.

谁能找到更权威的资料？
