Table 4 Correlations between serum and saliva

From: Steroid concentrations in antepartum and postpartum saliva: normative values in women and correlations with serum

  Antepartum (n = 28) Postpartum (n = 43)
  r r OBS r ZERO r LOD/√2
Estradiol .71** .41* .62** .59**
Estriol .71** -- -- --
Progesterone .65** -.06 .48** .40**
Testosterone .48**^ .29^ .59** .62**
Cortisol .30 .60** .60** .60**
DHEA .50** .65**^ .65** .65**
  1. * p < .05, ** p < .01.
  2. ^ = outlier removed.
  3. rOBS = observed correlation based only on samples with salivary concentrations > LOD; rZERO and rLOD/√2 = correlation based on all 43 women with statistical correction for samples < LOD.
