  1. Data presented as point estimate (95% CI)
  2. a Number of participants assessed by both the auxiliary nurse midwives and dentist
  3. b Number of sites with PD > 2 mm and BOP according to dentist’s measurement
  4. Validity measures comparing individual auxiliary nurse midwives to the dentist for probing depth ± 1 mm agreement and sensitivity and specificity of probing depth (PD) > 2 mm and bleeding on probing (BOP) classification
