ADIPOQ and stroke disorder: Based on the ROC curve, the optimal cutoff value of serum adiponectin levels as an indicator for diagnosis of moderate-to-high stroke was projected to be 7.0 μg/ml, which yielded a sensitivity of 63.6% and a specificity of 62.4%, with the area under the curve at 0.65 (95% CI 0.58–0.72).
