Participant Flow

This non-interventional study was based on Chinese acute ischemic stroke patients who had treatment from 2007 to 2017 from the existing data of the China National Stroke Registry (CNSR) I, II, and III to investigate the temporal trends of thrombolysis treatment in Chinese acute ischemic stroke patients.

All eligible patients who met all inclusion and none of the exclusion criteria from the existing data of China National Stroke Registry (CNSR) I, II, and III with treatment from 2007 to 2017 were included.
