# Could confounding factors unmask a significant relationship?

Suppose we have one dichotomous dependent variable and ten independent variables ( mix of categorical and continuous), by using a $$t$$ test and a $$\chi^{2}$$ test no relation was found between each independent variable and dependent variable.

After using binary logistic regression analysis relationship was found (p<.05) between one independent variable and dependent variable. What does this relationship mean?

Is this a false relationship? Could confounding factors unmask a significant relationship?!!
