Stanford et al. (2014) Impact of instruction in the Creighton model fertilitycare system on time to pregnancy in couples of proven fecundity: results of a randomised trial. Pediatric and Perinatal Epidemiology 28: 391-399.
Key Results
The adjusted hazard ratio for the influence of CrMS on TTP was 0.86 [95% confidence interval (CI): 0.53, 1.38]. Fecundability in cycles with intent to conceive was 31% in controls and 36% with CrMS (P = 0.32). By the first cycle, fecundability was 17% in controls, and 4% with CrMS (P = 0.02).
Conclusion
“We found no significant impact of CrMS on TTP or fecundability, but fewer of the women receiving CrMS conceived by the first cycle.”
