intcpt_RE: a column of 1's for model setup as a random intercept covariate.
smlves_NP: small vessel occlusive disease as a non-proportional odds covariate.
lvORcs_NP: large vessel atherosclerosis / cardioembolic stroke as a non-proportional odds covariate.
group: treatment group indicator.
time3: dummy variable to indicate 3 months of follow-up.
time6: dummy variable to indicate 6 months of follow-up.
time12: dummy variable to indicate 12 months of follow-up.
mrkprior: modified Rankin scale prior stroke onset.

lvORcs: large vessel atherosclerosis / cardioembolic stroke as a proportional odds covariate.
smlves.group: interaction term between smlves and group.
