Based on the descriptions there, it doesn't seem to me like the mentioned studies actually show meditation causing a clear benefit. That's not surprising to me, since most studies on meditation (like most lifestyle studies) fall into one of: 1) only describe observational correlations, not causation (such studies are useful for guiding further research, but are a poor basis for recommending lifestyle changes) 2) describe an intervention leading to a statistically significant change, but one whose practical significance is negligible, unsubstantiated, or an unclear mixture of benefits and drawbacks 3) quality too poor to draw any firm conclusion at all (too small, no control group, neglect of known likely confounders, blatant p-hacking, etc.)
