Hazard ratios for cancer mortality

Areas compared	Hazard ratio	95% Confidence Interval	P-value
Nishiyama region vs control area	0.90	0.65–1.24	0.51
Direct exposure area on the near side of the hypocenter vs control area	1.28	1.04–1.58	0.02
Direct exposure area on the far side of the hypocenter vs control area	0.96	0.74–1.23	0.73

Cancer mortality was evaluated by area adjusted for sex, age at the time of bombing, the shielding condition, and entering into the hypocenter areas within the 3 days following the bombing.
