A 2015 article in the American Journal of Public Health reports findings from a study on adherence to mammogram recommendations. As per the authors.
"For this study, we extracted and reviewed patient and provider data entered into electronic medical records during registration and health care visits from January
1, 2012, to December 31, 2013. Patients were eligible if they were cisgender women, transwomen taking estrogen for 5 or more years, or preoperative transmen;
were aged 40 to 67 years as of January 1, 2012, and attended 1 or more medical appointments at the center prior to participating in this study."
The primary outcome of interest is adherence to mammogram quidelines, defined as "having 1 or more mammograms during the 2-year study period"
The researchers also used simple logistic regression to estimate the associated between In(odds) of having adherence with the gender identity of each participant.
There are three categories of gender identity: cisgender female (reference), trans woman, and trans man (a female transitioning to a male). The model is as
follows
In(odds of adherence) = B, + B,1 + B,
where x1= 1 if subject identifies as a trans woman, O if not; x2 = 1 if subject identifies as a trans man, 0 if not (again, those who identify cisgender female are the
reference group)
In this model:B.
=1.0 and SE(B.) = 0.04; B, = =0.78 and SE(B,) = 0.32; 8, --1.0 and SE(B,) = 0.55;
%3D
-What Is the estimated proportion of trans men that adhered to the mammogram guldellnes?
a. 0.50 (50%)
b. 0.00 (0%)
C. 1.00 (100%)
d. This cannot be computed, because only odds ratios can be calculated from the results of logistic regression.
