  1. *excluded all near miss criteria according to WHO; risks are not estimated because they are not predictors nor outcomes.
  2. p-values reported derive from Chi-square tests.
  3. PR: prevalence ratio adjusted by cluster effect.
  4. Missing data: (a) = 773 cases; (b) = 562 cases; (c) = 449 cases; (d) = 972 cases.
  5. Values in bold mean they are statistically significant.
