title: Comment on 'facts and artifacts in the study of intra-uterine mortality: a reconsideration from pregnancy histories' by henri léridon(1).
abstract: Abstract   Extract   I have suggested that at a given birth order the probability of having a further pregnancy is greater when the last pregnancy had been spontaneously aborted than when it resulted in a birth.(2) Léridon,(3)in the course of a valuable paper on foetal wastage, presents data which, according to him, impugn my suggestion. I would like to question his claim.
