Comparison of the CT scan Evaluation Methods.*

Sequential Analysis Score of “0” Score of “1” Score of “2” Number of Readings
69 23 8 166
Consensus Analysis Score of “0” Score of “1” Score of “2” Number of Readings
64 26 10 400
*

The methodologies are designated as “Sequential Analysis”, where each scan was reviewed in series, and “Consensus Analysis” where each score was agreed upon by 3 simultaneous readers. The number of readings was calculated as the total number of CT interpretations. The kappa statistic for the correlation between these two methods (Kappa 0.84 95% confidence interval [0.73–0.94] P <0.0001 for the sequential and consensus scheme).
