a IRR is 1.46 (95% CI, 1.45 to 1.47) for depression relative to nondepression.
b IRR is 19.53 (95% CI, 17.31 to 22.09) for depression relative to nondepression.
cMatching-adjusted hazard ratio is 9.28 (95% CI, 7.82 to 11.0) for depression relative to nondepression.
d IRR is 9.38 (95% CI, 7.90 to 11.19) for depression relative to nondepression.
eMatching-adjusted hazard ratio is 1.64 (95% CI, 1.61 to 1.66) for depression relative to nondepression.
f IRR is 1.66 (95% CI, 1.64 to 1.68) for depression relative to nondepression.
Note. Follow-up period: depression, 11.5 years (mean), 11.8 years (median); nondepression, 10.3 years (mean), 9.5 years (median). IRR = incidence rate ratio; CI = confidence interval.
