The proportion of anemia among women in the evacuation area after the Fukushima Daiichi Nuclear Power Plant accident. Percent change with 95% confidence intervals in the age-adjusted proportion of anemia after the Fukushima Daiichi nuclear disaster was shown among women who received a health check in 2011. The proportion estimates between 2012 and 2018 were adjusted based on the 2011 age distribution. Cochran-Armitage trend test output 0.03 of the p-value. The dashed line indicates linear regression, which showed a declining trend (slope = − 1.3 × 10−3).
