Fig 1.
Map showing the geographical characteristics of disaster area and the change rate of physicians.
The size of the symbol for change rate represents the magnitude of the change. Air dose rate was measured within 80 km of the nuclear power plant and data were acquired from the Japan Atomic Energy Agency.
Table 1.
Demographic characteristics and number of hospitals and physicians in pre- and post-disaster year.
Table 2.
Population sizes and number of hospital physicians, classified according to the distance from the tsunami-affected coast and the nuclear power plant in 131 municipalities (municipality-based analysis).
Fig 2.
Distributions of distance from disaster site to each hospital in the pre-disaster year (hospital-based analysis).
(A) Distance from the tsunami-affected coast and (B) from the restricted area surrounding Fukushima Daiichi Nuclear power plant (FDNPP). IQR, inter quartile range (25th percentile, 75th percentile); SD, standard deviation.
Table 3.
Number of hospitals and physicians classified according to the distance from the tsunami-affected coast and the nuclear power plant in the pre- and post-disaster years (hospital-based analysis).
Fig 3.
Boxplots and scatter plots showing hospital physicians-to-population ratios against distance from disaster site.
(A) Distance from the tsunami-affected coast and (B) from the restricted area surrounding Fukushima Daiichi Nuclear power plant (FDNPP) (hospital-based analysis). Municipality-based population data were used, while physician data were hospital-based. Seven hospitals located within the restricted area were excluded from the analysis with tsunami-distances. In Fig A-1 and B-1, the whiskers represent the 1.5 * inter quartile range ± the 25th and 75th percentile. The black diamond represents the mean of all of the data. IQR, inter quartile range (25th percentile, 75th percentile); SD, standard deviation.
