I ignored your link after I saw that none of the page's claims , and with cause as explained previously. Find the original research. I need to look at the study designs. In my experience,including my recent experience on this thread, Christians shouldn't be trusted with statistics.http://m.blogs.christianpost.c om/biblical-spirituality/scien tific-studies-on-prayer-does-p rayer-really-work-13400/
Don't see "christianpost" and ignore it. That's an amalgamated list of reports of medical doctors on the efficacy of prayer.
Also, they listed the same data multiple times, such as two entries for "Ladies' Home Journal - December 2004 ... "The Healing Power of Prayer" by Kathryn Casey" and three for "The Healing Power of Prayer - November 29, 1998 by Parker Lee Nash, Staff Writer." After awhile, you just stop trusting the people generating such pages.
