IL4R and stroke disorder: Another study showed that plasma IL-4R level within 4.5 h after stroke onset was an independent predictor of poor neurologic prognosis with a sensitivity of 53.0% and specificity of 72.0% at 24 h and a sensitivity of 52.0% and specificity of 73.0% at 48 h after stroke onset using the same cutoff point of 503.40 ng/l (33).
