It's important to understand that scientific studies are generally studies of groups of people and the results may apply to most people in the group but not all of them. Think of the Bell Curve with the average or norm in the center and fewer people in each tail. Even when the results are distributed like this, usually indicating very strong results, there are still people in the tails, people for whom the results don't apply. In other words, as Kristine says, you have to figure it out for yourself, asking yourself are you one of those people for whom the results apply or are you one of those outliers? Your n=1 is more important for you than any result from a scientific study whose results characterize the group not each and every individual within the group.
