Table 1:

Comparison between self-reported gender identity disclosed in the sociodemographic survey versus information from the patient chart^*

Self-reported gender identity disclosed in the survey	Information from the patient chart
	Female, n (%)	Male, n (%)	Transgender or genderdiverse,† n (%)	Total, n (%)
Female	7759 (95.7)	72 (1.2)	40 (22.9)	7871 (55.2)
Male	31 (0.4)	5629 (94.3)	27 (15.4)	5687 (39.9)
Transgender, intersex or other‡	23 (0.3)	10 (0.2)	95 (54.3)	128 (0.9)
Prefer not to answer, don’t know or no answer§	292 (3.6)	256 (4.3)	13 (7.4)	561 (3.9)
Total	8105	5967	175	14 247

^*Counts smaller than 5 have been suppressed to reduce the risk of participant reidentification.

^†Patients who had an International Classification of Diseases, 9th Edition code for gender dysphoria (ICD-9 302.85) on their chart, added after a manual audit and validation with the most responsible provider.

^‡Transgender, intersex and other response options are not equivalent, but were combined to avoid disclosing cell counts smaller than 5. The transgender category was much larger than all the other categories.

^§“Prefer not to answer,” “don’t know” and “no answer” response options were combined to avoid disclosing cell counts smaller than 5. The “prefer not to answer” category was much larger than the “don’t know” category. The “no answer” data category includes respondents who started the questionnaire and did not finish it, but not necessarily because of the gender identity question.
