Evidence based medicine and prostate cancer screening

Evidence based medicine involves a practitioner using the best available clinical studies and their clinical judgement.
There have been several websites that have helped assimilate all the available information and give a conclusion in easy to read format for physicians and patients alike.
The Cochrane Collaboration is an international not-for-profit organisation, providing up-to-date information about the effects of health care.
They have several reviews about prostatic conditions including screening for prostate cancer.

no robust evidence from randomised controlled trials is available
regarding the impact of screening on quality of life, harms of screening,
or its economic value. Results from two ongoing large scale multicentre
randomised controlled trials that will be available in the next several
years are required to make evidence-based decisions regarding prostate
cancer screening.

This site applies appropriate strict criteria to choose which papers to use. As more clinical trials enter the literature, the conclusions should be more helpful.
My feelings about PSA screening were previously discussed, but as I state in my thoughts, my views are not unanimous.
