Table 4 Mean squared error (×100) in analysis sample C (women with density measured at 1 year and 2 years) {relative performance (95% CI)} for predicting density change at 2 years, using mean density change at year 1 (REF = reference predictor) or individual observed density change at year 1
| Â | Stratus % | Densitas % | Volpara % | NNVAS % |
|---|---|---|---|---|
Mean change T0–T1 | 6.0 {REF} | 21.4 {REF} | 4.2 {REF} | 12.0 {REF} |
Individual change T0–T1 | 14.5 {2.4 (1.6 to 3.3)} | 65.9 {3.1 (1.8 to 3.9)} | 10.0 {2.4 (1.8 to 3.0)} | 19.7 {1.6 (1.3 to 2.3)} |
