The study was published. If you have any reason to doubt that prayer did not benefit the patients then by all means discuss the study.

My remark, however, was addressed to what you said:
"The hospitals used, the skill level of doctors performing the surgeries.. there is no way this is accurate,...."

My statement was simple and straight-forward. Not too hard for anyone to understand. If the point of prayer is for a deity to intervene. Then the deity's intervention can not be related to the surgeon's skill.
