Logistic regression models to predict antimony treatment failure of ulcerative cutaneous leishmaniasis.

aOdds ratio and its 95% confidence interval of the simple logistic regression in the univariate analysis.bOdds ratio and its 95% confidence interval of the multiple logistic regression for the Prognostic Score 1. R2 = 0.54; 85 patients in the model.cOdds ratio and its 95% confidence interval of the multiple logistic regression for the Prognostic Score 2 (without inclusion of the Leishmania species). R2 = 0.38; 85 patients in the model.*This variable was log-transformed before the analysis.**Odds ratio obtained after pooling L. guyanensis and L. peruviana and comparing against L. brasiliensis.
