Brief Summary

Results: There were no significant differences between the control and affected periods in the prevalence (per 10,000 live births) of cleft lip with or without palate (13.8 versus 16.7; p=0.342), isolated cleft palate (5.2 versus 3.2; p=0.267), or overall cleft lip and/or cleft palate (19.0 versus 19.9; p=0.799). Conclusions: We did not observe that the 2011 Tohoku earthquake and tsunami affected the birth prevalence of CL/P in Miyagi prefecture, even though it severely impacted human health in the area.
