Consumption of 1 cup of coffee per day decreased the risk by 13% (however, this finding was statistically significant), consumption of two to three cups per day resulted in a decrease risk of 42% and finally consumption of four or more cups per day reduced the risk by 47%, almost half.

Other studies in the past has shown similar results, however the importance of this study is that it showed that both caffeinated and decaffeinated coffee produce these results. I addition to that it was shown that although filtered coffee and instant coffee have similar beneficial results, the consumption of espresso or percolator coffee did not significantly reduce the risk.
