Time Course of Cerebrovascular Reactivity in Patients Treated for Unruptured Intracranial Aneurysms: A One-Year Transcranial Doppler and Acetazolamide Follow-Up Study

Figure 2

Box plots comparing change in mean cerebrovascular reactivity (CVR) from the first examination to follow-up in patients treated with coiling and clipping. Boxes extend from the 25th to the 75th percentile. Horizontal bars represent the median, and whiskers extend to the most extreme point that is less than 1.5 times the interquartile range from the box. Mean values are marked with crosses, and a single outlier is depicted as a circle.
