* After at least 21 days of hypothermia. The "zero" point is the last day of hypothermia, following [Vincent 1964].
** Pregnancies of at least six weeks duration in a given cycle.
*** Of which 48 (25%) early losses within six weeks and 15 clinical spontaneous abortions after six weeks from the onset of the last menses
**** The same set of data as in ***, but excluding the 48 early losses (i.e. within 6 weeks of LMP). The probabilities used to generate the figure in [Wilcox, Weinberg, and Baird 1998] were kindly provided by Dr. David Dunson.
***** Ongoing at 60 days from the onset of the last menses, included clinically diagnosed abortions in this period (window around BBT reference day).
