Values in the columns relating to whether women had any knowledge of recommended GWG are based on information from 164 women (74 who reported having knowledge of recommended GWG and 90 who reported having no knowledge of recommended GWG) after excluding 17 women who were <37 weeks gestation at delivery and an additional 10 women who had incomplete information in medical records. Meanwhile, values in the columns relating to whether women had correct knowledge of recommended GWG are based on information from 74 participants (36 who reported correct knowledge of recommended GWG and 38 who reported incorrect knowledge of recommended GWG) after excluding seven women who were <37 weeks gestation at delivery and an additional seven women who had incomplete information in medical records.
