Contribution

Help with this project will be greatly appreciated! If you see a false positive or false negative that isn't already in changed_studies.txt, it would be appreciated if you made a pull request fixing them. Right now this project focusses only on false negatives, so if someone who is qualified and is willing to help fix the false positives, you can send me a message. Together we can make MURA better :)
