Treatment status
Periodic clinic visits, new	29 (14.5)	9 (8.3)	20 (21.7)	0.007
Periodic clinic visits, discontinuation	7 (3.5)	3 (2.8)	4 (4.3)	n.s.

Median of change (interquartile range) or number (percentage) are shown.
n.s., not significant.
^a Mann–Whitney U or Pearson chi-square tests were performed to compare numerical data or proportions between the tsunami and radiation groups, respectively.
^†p < 0.05 and ^‡p < 0.01 for paired comparison between pre-quake and post-quake values using Wilcoxon matched-pair signed-rank test (Additional file 3: Table S2).
BMI, body mass index; HDL, high-density lipoprotein; LDL, low-density lipoprotein.
