Predictive performance of linear discriminant analyses (LDA) and artificial neural networks (ANN) in recognizing atrophic body gastritis patients with and without thyroid disease (%)
| Sensitivity | Specificity | Mean accuracy | |
| LDA | 60.8 | 58.1 | 59.4 |
| Standard ANN (29 variables) | 69.0 | 59.8 | 64.4 |
| T&T and IS (24 variables) | 78.8b | 70.5 | 74.7 |
| TWIST protocol (16 variables) | 81.8d | 69.9 | 75.8 |
P < 0.01 vs LDA;
P < 0.001 vs LDA and vs standard ANN P < 0.05.
