NOTE. RR^fem, Relative risk for females compared with males; CI, confidence interval; χ², chi-squared.

^aMR, mortality rates per 100,000, note all-cause mortality includes deaths with undetermined cause, and are thus higher than combined communicable and non-communicable disease mortality rates.

^bχ² LT, chi-squared for linear trend.

^cMHRR, Mantel Haenszel weighted relative risk, and Greenlands-Robins 95% confidence intervals.
