Effect of Age on Reliability of CT Read
| Age | # of patients | # of screws | Inter-observer ICC (UCL-LCL) | Intra-observer ICC (UCL-LCL) |
|---|---|---|---|---|
| <18 years | 12 | 156 | 0.24 (0.51-0.04) | 0.25 (0.51-0.39) |
| 18-60 years | 4 | 53 | 0.37 (0.58-0.17) | 0.61 (0.60-0.19) |
| >60 years | 7 | 52 | 0.16 (0.42-0.39) | 0.19 (0.47-0.45) |
ICC = Intraclass correlation coefficient; UCL = 95% upper confidence limit; LCL = 95% lower confidence limit; 261 of 286 screws were available for studying the effect of age on the inter- and intrarater ICC.
