aCovariates contribution (%) = reduction of (positive %) or increase (negative %) in HR computed with the following formula: (HRmodel 1 − HRextended model) /(HR model 1 − 1).
bSee Table 2.
Note: The age-adjusted HRs were nonsignificant for boys (1.58, 95% CI 0.89–2.80, and 1.28, 95% CI 0.56–2.92, respectively).
