A:Comparison of serum PDCD4 levels between patients with mild and moderate⁃to⁃severe neurological impairment in acute ischemic stroke(AIS)
(P < 0.001). B:Scatter plot showing the correlation between serum PDCD4 levels and NIHSS scores in AIS patients. C:Comparison of serum PDCD4
levels between AIS patients with good and poor prognosis(P < 0.001). D:Distribution of modified Rankin Scale(mRS)scores in AIS patients stratified
by high and low PDCD4 levels. E:Correlation between serum PDCD4 levels andneutrophil⁃to⁃lymphocyte ratio(NLR)in AIS patients.F:Correlation be⁃
tween serum PDCD4 levels and high⁃sensitivity C⁃reactive protein(Hs⁃CRP).G:Correlation between serum PDCD4 levels and procalcitonin(PCT).
