Fig. 2From: Quantification of cell-free DNA for evaluating genotoxic damage from occupational exposure to car paintsMean and 95 % confidence interval of cfDNA concentrations by range of exposure time in the exposed cohort. Exposure time to airborne solvent vapors significantly increased the extent of DNA damage assessed by cfDNA concentration (r = 0,28, p = 0,053, Spearman rank correlation)Back to article page
