Fig. 1 — Forest plot of prefecture-specific relative risk estimates.

Prefecture-specific estimates are reflected by the horizontal error bars. The dotted black line crossing the prefecture-specific estimates are set at RR = 1. The lowermost diamond-shaped symbol represents the pooled effects estimate. Majority of the prefectures indicate a negative association of COVID-19 pandemic and the risk of HSAD, except for Kumamoto, whereby risks were found to be positively and statistically significant.
