Log odds ratios with Class 1 as the reference class.

Bias-Corrected Beta (SE) p-value; P-values are shown where p<0.10. Estimates can be translated to odds ratios by exponentiation; 95% confidences intervals for odds ratios can be obtained by constructing the interval for the log odds ratios and the exponentiating the upper and lower bounds.
