Sir: A common explanation for the higher suicide rate in males is that men prefer violent and highly lethal methods.

However, few studies have explored how suicide sex ratios vary according to the interactions between methods of choice and mental illness. This study examined how such an interplay determines the male-tofemale suicide sex ratio in Taiwan.
