Those studies were mostly from the 80s-2000s when things were really different. Kids were often referred just for being gender nonconforming (like boys playing with dolls), not necessarily having serious gender dysphoria. Plus the treatment back then was often trying to make kids more "gender typical" - which obviously might push some kids toward appearing to "desist" even if they still had gender issues. Many of the kids in those studies didn't even meet what we'd now consider the criteria for gender dysphoria. So saying "80% of trans kids desist" might be more like "80% of gender nonconforming kids don't turn out to be trans" - which is pretty different.
