I read the article, very interesting results, on an important area of study. I was interested to see the useful graph showing compared results of different gender groups, transgender men, transgender women, cisgender women, cisgender men and nonbinary people, which showed significantly different results between those usefully delineated groups.
The levels of trauma found are indeed very concerning, and an important area for study.
As a side issue, I was also interested to see that there was no difference between the results of self diagnosed autistic people and those professionally diagnosed, implying self diagnosing people in this research at least, are getting it right about themselves.
