Yes I think it is the same data set. If I can be arsed I will analyse the full data. I am expecting it to be bullshit, and someone will likely get there before me, maybe Malcolm Clark or Michael Biggs after they picked apart Turban’s pile of crap.
I succumbed to curiosity and went to read it, but it's not on scihub so I can't get too sucked in, thankfully!
An article linked above says Adjustments were also made for sociodemographic factors including age, education level, employment status, household income, and race.
Is it actually possible that they didn't control for sex? Even if they had to call it 'sex assigned at birth' or whatever. If they didn't then that's all the information we need to conclude the study is trash. They should really have sex-disaggregated the data, but not to even control for sex? Yikes.
The other thing it looks like they missed is age at transition- they may be effectively comparing early transitioners (who are likely to have already had surgery) to later transitioners and finding that the later transitioners are less stable.
