Read abundance relationship with concentration values of L. pneumophila. Data retrieved after spike-in of two water samples (nuclease-free water (black) and drinking water (hatched)) and graphically represented as bars. A logarithmic regression model elucidates the relationship between the two variables (nuclease free water, y = 3948ln(x) – 14338; drinking water, y = 3824ln(x) – 14063). Logarithmic curves exhibiting the correlation in nuclease-free water (solid line, R2 = 0.88) and drinking water (dashed line, R2 = 0.89) samples are also shown. Y-axis data presented as mean ± SD after analysis of triplicates. Note the x-axis in log scale
