Stroke: Sensitivity and Specificity

Introduction: aka cerebrovascular accident. Mostly ischemic, some hemorrhagic. CT detects hemorrhagic stroke with high sensitivity. For history/physical findings to distinguish ischemic from hemorrhagic, see Hemorrhagic Stroke.

The sensitivity and specificity of findings for Stroke are listed below. See the left navigation bar to change the display.

Pre-Test Probability (Prevalence): %. Post-Test Probability (Predictive Value): %. Switch to display mode.
**Note that calculating probabilities from more than one finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)
