Computer Based Correlation of the Texture of P63 Expressed Nuclei with Histological Tumour Grade, in Laryngeal Carcinomas

Table 3

Contingency table of predicting the grade of laryngeal squamous cell carcinomas by the nonlinear logistic regression equation.

LG^+	LG^−	HG^+	HG^−	% overall accuracy	Cohen-Kappa	AUC
16	5	31	3	85.5	0.654	0.87

LG⁺ and LG⁻ refer to low grade (grade I) of correctly and incorrectly predicted carcinomas and HG⁺ and HG⁻ refer to correctly and incorrectly predicted high grade (grade II + grade III) carcinomas, respectively. AUC: area under the curve; overall prediction accuracy was estimated by the LOO cross validation method.
