Message

  Uncertainty intervals (profile-likelihood) and p-values (two-tailed)
    computed using a Wald z-distribution approximation.

  The model has a log- or logit-link. Consider using `exponentiate =
    TRUE` to interpret coefficients as ratios.

  Some coefficients are very large, which may indicate issues with
    complete separation.

Message

  Uncertainty intervals (profile-likelihood) and p-values (two-tailed)
    computed using a Wald z-distribution approximation.

  The model has a log- or logit-link. Consider using `exponentiate =
    TRUE` to interpret coefficients as ratios.

  Some coefficients seem to be rather large, which may indicate issues
    with (quasi) complete separation. Consider using bias-corrected or
    penalized regression models.
