Research on schizophrenia

This article is very interesting:

• St Clair, D., M. Xu, P. Wang, Y. Yu, Y. Fang, F. Zhang, X. Zheng, N. Gu, G. Feng, and P. Sham. 2005. "Rates of Adult Schizophrenia Following Prenatal Exposure to the Chinese Famine of 1959-1961." Journal of American Medical Association 294:557-562.

But my results do not support their findings. Worth some further exploration.
