OBJECTIVE: To study the regional correlation analysis of birth defects in Heshun county, Shanxi province from 1997 to 2001. METHODS: Exploratory data analysis, especially the parallel coordinate plot (PCP) method, and geographic information system were used to analysis the regional correlation of birth defects. In this paper, we selected 1997 to 2001 five groups variables of birth defects to plot the PCP. RESULTS: Yangguangzhan and Hengling have stronger positive correlation on the region. Liyang and Niuchuan have weak correlation. Yixing and Songyan have no correlation and other towns have no positive correlation on the region. CONCLUSION: The results indicate that this studied region has the regional correlation of birth defects.
