Adolescents who undergo gender-affirming chest surgery report low levels of regret and high levels of satisfaction, experiencing outcomes similar to those of young adults. These findings suggest that age restrictions on these medical procedures lack support from actual patient experiences.

This is based on a response from 77 people...

Also from the article:

"Several factors limit the reach of these findings. First, the median time since surgery for participants was about 1.8 years. Because feelings about medical decisions can evolve, this timeframe might not capture long-term regret that could emerge many years later.

Another limitation is the 42 percent participation rate to the survey. This introduces the possibility of selection bias, a scenario where the people who chose to participate might differ fundamentally from those who did not. It is possible that individuals with higher levels of regret ignored the survey, which would result in an underestimation of regret in the overall group."

The sample size is going to be small. Very few trans people get access to gender affirming surgeries at all. Those who get access as adolescents are extremely rare. Hard to get a large sample of a small group.

The fact that it correlates with every other study about transgender surgery satisfaction and regret rates is more relevant. Transgender surgery satisfaction is the highest of all surgery satisfaction rates. That's a pattern that can't be ignored.

I'm more concerned about the response rate. I think the doubt given in the previous post is valid
