You should be aware that the "CSM Mantra" (?) and "TM" meditation are very fringe forms. When most people say "start meditating" they're generally not referring to those. I personally consider TM to be neutral-to-harmful and I've never heard of this CSM Mantra until just now.

Mindfulness meditation, which is the only form tied to the 2,500 years of Buddhist meditation tradition, did ok.

Interesting is the graph of the results where you see the mindfulness meditation fared better than the "mantra" meditations pretty much across the board (even though most of it wasn't statistically significant.)
