a study that compares the vaccination schedules of patients with autism to those of patients without autism would be an example of a
case - control study.
cohort study.
meta - analysis.
pseudoscientific study.

Explanation:

A case - control study compares individuals with a disease (cases, here patients with autism) to those without the disease (controls, patients without autism) to look at exposures (vaccination schedules in this case). A cohort study follows a group over time, a meta - analysis combines results from multiple studies, and a pseudoscientific study lacks scientific validity. This study fits the definition of a case - control study.

Answer:

case - control study.
