The proper context
"To put this in context: a sample of 25 students is almost double the sample size that Andrew Wakefield used to prove the link between vaccination and autism."
I'm sure you are aware of the actual context, but unfortunately there are still a lot of people who genuinely believe that Andrew Wakefield's proof is valid : I guess that is the point of writing this the way you did, but the fact remains that the consequences for the children of the believers is often quite appalling and I would suggest that a more plain and straightforward statement of the context would do these children a favor.
