Uncorrected relative Risks (RR; points with associated values) and their exact 95 % confidence intervals (vertical lines) for Leptospira IgG sero-positivity (“exposed” vs. “non-exposed”), using different exposure groupings of “rat contact”. The data were collected in the course of the population-based cross-sectional zoonosis study from April 2008 to December 2009 by the Baden-Württemberg State Health Office Baden-Württemberg, Germany. The horizontal line marks RR = 1. The allocation of the subjects to the groups of “exposed” and “non-exposed” is displayed above and below the graph
