2cents,
Let’s try a different angle.
Here’s the argument made by the study.
If the MMR was a trigger, the rate of the No-MMR group should be 1:500, not 1:113, which is within range for the yes-MMR group.
Meaning, why is the phantom 1:500 ratio not displaying itself inside the no-MMR group? Must be, it’s not true.
For this to be a valid argument, you need to accept the following assertion:
>> The powers to be, controlling genetically-triggered Autism, take your vaccine status into account. If you have No-MMR, they will inflict Autism on only 1:500 specifically within your No-MMR group.
Therefore, the argument can be made, that the rate for the no-MMR group should be 1:500, not 1:113.
If you reject the above assertion, then the argument falls apart.
Since the powers to be, controlling genetically-triggered Autism, ignore your vaccine status, it triggered Autism throughout the whole 95k group at a rate of 1:500. 68 of those children happened to be non-MMR.
If we see 1:108 in the yes-MMR group, that is an association between MMR and higher Autism – in this hypothetical 1:500 example.
Is it any clearer now?
