I have proportions of health service use (several different types) across 4 years. All types of health services appear to be increasing over time. I wonder if it is possible to do a trend analysis with just 4 data points... (and if so, which test should be used?) Each year contains between 20k-40k subjects, and my analysis is for descriptive purposes.
