How would I code this in SAS?
I have a mean at baseline (score_0) 3 months (score_3) 6 months (score_6) 9 months (score_9) and 12 months (score_12)
would I run a proc anova?
What is the research question you are trying to answer?
Please be a bit more detailed that "analyze data".
If these are truly 'paired', i.e., you have a measurement on subjects at the 5 timepoints presented, then you ought to consider doing a repeated measures ANOVA. See example https://documentation.sas.com/?cdcId=pgmsascdc&cdcVersion=9.4_3.4&docsetId=statug&docsetTarget=statu... .
if your data do not have normally distributed independent errors, you may need to try something like this.
