Artificial neural networks in the recognition of the presence of thyroid disease in patients with atrophic body gastritis

Table 2 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

^bP < 0.01 vs LDA;

^dP < 0.001 vs LDA and vs standard ANN P < 0.05.
