Relationship between the thyroid nodularity and the ¹³¹I ground deposition in the locations of residence after the nuclear accident.

aValues of individual subjects were determined based on the data shown in Figure 1. bThe sum of the numbers of solid nodules and cysts in each subject. cMedian (IQR). Non-parametric multiple comparison test with Kruskal-Wallis test was employed to analyze whether the 131I ground deposition differed as a function of the total number of nodules and the number of solid nodules or cysts. dSignificantly different from the “zero-nodule” group (P = 0.007). eSignificantly different from the “zero-cyst” group (P = 0.004). Relationship between the thyroid nodularity and the 131I ground deposition in the locations of residence after the nuclear accident.
