Am J Obstet Gynecol. 1992 Dec;167(6):1563-4. doi: 10.1016/0002-9378(92)91740-2.

Abstract

Saliva specimens were collected approximately every 6 hours from day 280 to day 294 by 16 women who labored on day 294. There was a normal rise in the mean saliva estriol/progesterone ratio in the six who went into labor spontaneously but no change in the 10 whose labor was induced.
