But the whole title is basically misleading.

In that data there is no statistical difference between any of the ethnicities and whites, with the exception of the indigenous category, which has a confidence interval so wide that it must have a tiny sample size.

This study is powered to show that whites who used psilocybin and MDMA have lower rates of MDE (and last year only for hispanics) and that indigenous have a slightly higher rate of MDE compared to whites.

This study is just underpowered to show a difference in most of the ethnicities. Many of them probably show similar responses if you have enough of a sample size, and a confidence interval that crosses 1 just shows that you can't read anything into it.
