Does anyone know if there is any other research around the safety of nicotine patches in pregnancy or if the outcome of the SNAP trial has been published?

I have have come across the study protocol but I haven't seen if there are any results.

Coleman, T., Thornton, J., Britton, J., Lewis, S., Watts, K., Coughtrie, M. W., et al. (2007). Protocol for the smoking, nicotine and pregnancy (SNAP) trial: double-blind, placebo-randomised, controlled trial of nicotine replacement therapy in pregnancy. BMC Health Serv Res, 7, 2.
