*Gender was measured using the two-step method via open-ended response where participants were first asked their gender and then their sex assigned at birth.

†Race and ethnicity information were collected via open-ended responses to allow for self-identification rather than forcing participant responses into predetermined categories which may not address how participants self-identify.

NR, not reported; TGD, transgender and gender-diverse.
