The MBSR studies are two-month interventions. They are not going to have the same strong effects as people meditating seriously for years.
On the other hand, those studies that investigate people who meditate a lot are often from a monastic setting where people have teachers which is quite different from someone meditating without a teacher and orienting themselves with the Mind Illuminated.
Maybe meditation moves people in a random direction. Those who get hurt, mostly stop meditating, so you won’t find many of them in the “meditating seriously for years” group.
