For respiratory tract infection, RRR 1.006 (95% CI: 1.0004, 1.01). The RRR (relative risk ratio) is the ratio of relative risk for women to the relative risk for men.10

Asthma 77 counties included; peripheral vascular disease 140 counties; all other causes 213 counties.

For cardiovascular disease, RRR 1.004 (95% CI: 1.0008, 1.007).

4

For heart rhythm disturbance, RRR 1.01 (95% CI: 1.004, 1.02).
