My attention was recently draw to a blog post labeled “108 Benefits of Daily Meditation.” It didn’t take me long before I found something that made me feel uneasy, example number three to be exact:
What surprised me was the chart. It does not appear in the cited paper. The chart lacks an explanatory note, but the normal interpretation would be that it is comparing the effects of different interventions on blood pressure change. The horizontal lines represent the 95% confidence interval around some effect size. If the line crosses zero then we say that the findings were not statistically significant. Thus, the blog post included a chart that contradicts the findings of the cited paper.
