In India, various systems of Health care exist and the choice is left to patients for approaching particular type of system. Most of the doctors will favour their own system of medical care. So is there any way to find out neutrally about which one is good for what? Millions of patients are treated daily all over the world and in spite of technology we are not able to judge that which pathy is good for what?

What are the basic rules of lifestyle which leads to good health? I would like to know result of large data set for comparison of various system of Healthcare. My question: Do you have comparative study of various systems of health care for health promotion and treatment of various diseases?
