Correction: Effect of Neuroimaging Studies on Acute Ischemic Stroke
Scott Allen, MD
1 September 1996 | Volume 125 Issue 5 | Page 428
TO THE EDITOR:
Salerno and colleagues [1] report that of their total sample of 206 patients, the class of stroke was "unknown cause" in 67 patients (32.5%). Classification was based on the results of the physical examination at presentation, the first neuroimaging study, and any ancillary tests done before a second neuroimaging study. They also report that of patients who had only one neuroimaging study, 23 cases (35.4%) were initially classified as having an unknown cause. According to the data presented in Table 3, 75 (53.6%) of the patients who had two or more neuroimaging studies were classified as having an unknown cause. The sum of these two groups (23 + 75) is far greater than the reported overall group (n = 67). This suggests a possible error in the reporting of their data.
