That's another study that was done in the United States, with a very small sample size. If I were being critical of the study, I would say it's an extremely small sample size. You can't really generalize from it.
The problem is there is just so little empirical data. People are not collecting the data such that it can be presented. That's why the study by Jeff Nisker is important, because it's Canadian, it's recent, and it was done with a certain degree of thoroughness. But the criticism could be that it's one clinic.
We just don't have a lot of data, but we do know people change their minds, and I'm asking that people retain that right to the last possible moment.
