From: Association between a single mother family and childhood undervaccination, and mediating effect of household income: a nationwide, prospective birth cohort from the Japan Environment and Children’s Study (JECS)

  1. Estimates are risk differences, except for the proportion mediated
  2. “Rho at which ACME = 0” refers to the sensitivity parameter, rho at which the CI of ACME includes zero. The model was adjusted for maternal age and educational level
  3. CI confidence interval, ACME average causal mediation effect, ADE average direct effect
  4. aCalculated with the dataset with missing data imputed (n = 82,462)
  5. bCalculated with the complete case dataset (n = 72,612)
