From the book, "The Case for Miracles," by Lee Strobel.
Dr. Candy Gunther Brown, who earned her doctorate degree at Harvard University, is a professor of religious studies at Indiana University. She has a neutral outlook on religion, having said, “I do not assume the existence or nonexistence of a deity or other suprahuman forces.”
Brown cites two scientific, peer-reviewed studies that confirmed the efficacy of prayer on patients. She noted, “One of the first publicized studies was by Dr. Randolph Byrd, published in 1988, in the peer-reviewed Southern Medical Journal. It was a prospective, randomized, double-blinded, controlled study of four hundred subjects.” The results: “Patients in the prayer group had less congestive heart failure, fewer cardiac arrests, fewer episodes of pneumonia, were less often intubated and ventilated, and needed less diuretic and antibiotic therapy.” The editor of the Journal noted that the study had been peer-reviewed and was judged to be a properly designed and executed scientific investigation.
THEN, a decade or so later, a REPLICATION STUDY by Dr. William S. Harris and colleagues was published in the “Archives of Internal medicine.” Dr. Brown noted of this study, “This was a ‘gold standard’ study of the effects of intercessory prayer on almost a thousand consecutively admitted coronary patients. Half received prayer, the other half didn’t. And again, the group that received prayer had better outcomes than the control group. These studies affirmed that the recipients of prayer had better outcomes than those who didn’t receive prayer.” - "The Case for Miracles," by Lee Strobel, pages 123-128
Discussion -
Here are your prayer studies.......not noteworthy at all. Also, other studies have shown no effect. Anyway, I would hardly call the fact that some of the patients had fewer complications an indication that a god was involved. If they had gotten up and walked out of the hospital the next day healed, that would be something.
A 1988 study by Randolph C. Byrd used 393 patients at the
San Francisco General Hospital coronary care unit (CCU). Measuring 29 health outcomes using three-level (good, intermediate, or bad) scoring, the prayer group suffered fewer newly diagnosed ailments on only six of them. Byrd concluded that "Based on these data there seemed to be an effect, and that effect was presumed to be beneficial", and that "intercessory prayer to the Judeo-Christian God has a beneficial therapeutic effect in patients admitted to a CCU."
[6] The reaction from the scientific community concerning this study was mixed. Several reviewers considered Byrd’s study to be well-designed and well-executed,
[7] while others remained skeptical. A criticism of Byrd's study, which also applies to most other studies, is the fact that he did not limit prayers by the friends and family of patients, hence it is unclear which prayers, if any, may have been measured.
[8]
The Byrd study had an inconsistent pattern of only six positive outcomes amongst 26 specific problem conditions. A systematic review suggested this indicates possible
Type I errors.

A 1999 follow-up by William S. Harris et al. attempted to replicate Byrd's findings under stricter experimental conditions, noting that the original research was not completely blinded and was limited to only "prayer-receptive" individuals (57 of the 450 patients invited to participate in the study refused to give consent "for personal reasons or religious convictions").
[9] Using a different, continuous weighted scoring system – which admittedly was, like Byrd's scoring, "an unvalidated measure of CCU outcomes" – Harris et al. concluded that "supplementary, remote, blinded, intercessory prayer produced a measurable improvement in the medical outcomes of critically ill patients", and suggested that "prayer be an effective adjunct to standard medical care."
[10] However, when they applied Byrd’s scores to their data, they could not document an effect of prayer using his scoring method. Critics have suggested that both Byrd's and Harris's results can be explained by chance.
[11] Richard P. Sloan compared the Byrd and Harris studies with the
sharpshooter fallacy, "searching through the data until a significant effect is found, then drawing the bull's-eye."
