Results from the BM test.

	0% morph images pre-treatment	0% morph images post-treatment	BM index pre-treatment, 0.5 s exposure	BM index pre-treatment, 2 s exposure	BM index post-treatment, 0.5 s exposure	BM index post-treatment, 2 s exposure
Cis controls (n = 15)	2.9 ± 1.1		26.0 ± 15.5	29.3 ± 18.0
TrM (n = 40)	1.96 ± 1.0	2.8 ± 1.0	− 14.9 ± 32.8	− 6–5 ± 63.3	− 21.3 ± 21.1	− 24.5 ± 49.9
TrW (n = 25)	1.85 ± 1.0	2.4 ± 1.0	− 13.8 ± 29.5	− 8.8 ± 57.6	− 21.2 ± 24.1	− 22.6 ± 45.7

Ratings for 0% morphed (unaltered) images ranged from 0 (not me at all) to 4 (entirely me). Positive values on the BM index indicate greater self-identification with their body morphed to other bodies that are the same as their birth assigned sex (as seen in cis-controls); negative values indicate greater self-identification with their body morphed to other bodies that are the opposite to their birth assigned.
