Fig. 1

Seasonality of mortality for Japan as a whole, obtained by pooling 47 prefecture-specific estimates without (blue) and with (red) temperature adjustment. The seasonality, here referring to the association between the day-of-year and mortality, is computed as the relative risk (RR) of mortality estimates at each day to the minimum mortality estimate at the trough with 95% confidence intervals (95%CIs): \( \mathrm{RR}=\frac{\mathrm{Mortality}\ \mathrm{estimate}\ \mathrm{at}\ {\mathrm{day}}_{\mathrm{i}}}{\mathrm{Minimum}\ \mathrm{mortality}\ \mathrm{estimate}\ \mathrm{at}\ \mathrm{the}\ \mathrm{trough}} \)
