	Q24: For me, undergoing screening to determine if I was a carrier for GD was:	n=66 1.42 (0.725)	n=64 1.53 (0.959)	n=63 2.24 (1.266)
For questions 25 to 28, imagine you were found to be a carrier for GD	Q25: Imagine that your results from carrier screening showed that you were a carrier for GD. Learning that you were a carrier for a mutation causing GD would have been:	n=71 1.48 (0.876)	n=68 1.46 (0.905)	n=68 4.03 (1.133)
	Q26: Imagine that prior to deciding to have carrier screening, a health care provider informed you that carriers of GD have a 10% risk of getting PD during their lifetime. Getting that information in that way would have been:	n=70 1.86 (0.952)	n=68 1.88 (1.127)	n=69 3.46 (0.994)
	Q27: Now imagine that after learning that you were a carrier for GD, a health care provider informed you that carriers of GD have a 10% risk of getting PD during their lifetime. Getting that information in that way would have been:	n=67 1.88 (1.094)	n=69 1.59 (0.990)	n=68 4.10 (0.964)
	Q28: Now imagine that after learning that you are a carrier for GD, you read an article that says carriers of GD have a 10% risk of getting PD during their lifetime. Getting that information in that way would have been.	n=69 2.78 (1.533)	n=67 1.76 (1.046)	n=71 4.21 (1.133)
