The risk factors related to dysphagia in patients with RSSI included the following: High-sensitivity C-reactive protein (hs-CRP) (OR = 1.076, 95% CI: 1.005–1.153),baseline National Institutes of Health Stroke Scale (NIHSS) score (OR = 1.230, 95% CI: 1.132–1.336), total CSVD burden (OR = 1.613, 95% CI: 1.195–2.177) and lesion region(OR = 4.462, 95%CI: 2.333–8.532). Here, CRP is linked to Stroke.
