Table 1 Results of the logistic regression for the river samples, assessing the effects of precipitation, river depth, river pH, and river identity on the likelihood of detecting Leptospira. Significance of coefficients (slopes and intercepts) was evaluated with an alpha = 0.05

From: Leptospira in river and soil in a highly endemic area of Ecuador
