  • ND indicates not done.

  • * See Evidence Tables 4, 5, and 6.

  • Arc refers to the influence diagram (see Fig. 2).

  • Weighted estimates computed by pooling the numerators and denominators of the target arms.

  • § Some studies involved more than 1 arm.

  • The median late-term rate is 0.3.

  • Without outlier (target article 23; 839 986 subjects), the mean (SD) sample size is 45 609 (43 141).

  • # The SD was calculated by using a continuity correction.
