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).
