        RANDOMISED CLINICAL TRIALS - CONCLUSION
How important are these statistically significant differences to real live people? This is a question that many doctors neglect to ask themselves or to allow their patients to decide. I have heard doctors claim that a treatment involving five different injections which caused nausea, low blood counts, hair loss and many other unpleasant side effects was 'better' than a treatment consisting only of tablets with very few side effects. The first treatment was 'better' because it produced a statistically significant improvement in the average length of life— three months longer than with the tablets. So when your doctor recommends a certain treatment, telling you that research has shown it to be the 'best', make sure you find out just what this means and what the alternatives are. Given all the information about each treatment, you may or may not agree with your doctor's conclusion.
