I've always wondered why data for some huge meta-analysis studies isn't availabe. If you're not a researcher you can practically never verify the result that there's no link between vaccines and autism, or any other similar studies. Most of these are just number crunching (increased risk of diet influencing disease, intervention experiments in psychology, medicine etc.), yet the number crunching is concealed and the numbers are the only thing presented, and I should trust the researchers that they didn't play with the numbers.
