The objectives of the paper titled “Short and Long Term Mortality Rates Associated with First Pregnancy Outcome: Population Register Based Study for Denmark 1980-2004” were to examine mortality rates associated with first pregnancy outcome and to explore differences in mortality rates associated with early abortion and late abortions (after 12 weeks). The population was comprised of a total of 463,473 Danish women who had their first pregnancy between 1980 and 2004 (2,238 died across the study period).
