The association and influence of the clinical variables enumerated in the first column on the sensitivity of the hydatid fluid (HF)-, B2t- and 2B2t-ELISAs and of a commercial IHA kit was statistically assessed. B-OR: odds ratio in the bivariate, and M-OR in the multivariant regression analysis. IC: 95% confidence interval. Statistically significant differences (P≤0.050) are shown in the table (in bold). tr.: treatment.
