Distribution of numbers of unique patients (out of 123 441 total) who selected various combinations for Legal Sex, Sex Assigned at Birth, and Gender Identity. Out of 168 possible combinations, 88 combinations did not occur in the data set. Four of the possibilities for Sex Assigned at Birth were not seen for any patients with Legal Sex of “Unknown”; thus, those rows are not shown. The colored boxes indicate categories that were predicted to be high likelihood of being gender-expansive (green), possibly gender-expansive (yellow), or likely >95% cisgender (orange). “Blank” indicates that the patient did not select an option. Abbreviations (all apply to SOGI fields): Not recorded, “Not recorded on birth certificate”; Not disclosed, “Choose not to disclose”; M, “Male”; F, “Female”; TM, “Transgender male”; TF, “Transgender female”; NB, “Nonbinary.”
