^*We adjusted for age (5 year categories) and occupations. We further adjusted for time-trends in the overall model.

^†The range of adjusted ORs for mortality in each prefecture is shown. The reference is the grand mean of all the prefectures.

^‡The variance between 46 prefectures is shown because the data for Okinawa prefecture were not available in 1970.
