Why the study?
Proteinuria is a known risk factor for cerebral infarction that can change over time, but data on the association between changes in proteinuria and cerebral infarction risk were scarce.

Proteinuria trajectory may refine cerebral infarction risk assessment; leaves open whether modifying proteinuria alters incidence in trials.
Does a change in proteinuria status affect the risk of cerebral infarction in a Korean population?
Any history of proteinuria, even if resolved, is associated with an increased risk of cerebral infarction compared to persistently negative proteinuria.
