Figure 3. Day 22 weight in a/a (wild-type) animals across exposure groups.

Figure 3

A linear increase in mean weight with increasing lead exposure was found in males (p = 0.04) but not females (p = 0.83) in a/a (wild-type) animals (n = 144). Among males, the mean weight for 0 ppm was 8.55 g (1.10 standard deviation [SD]), the 2.1 ppm group measured 9.14 g (1.15 SD), the 16 ppm group measured 9.51 g (1.22 SD) and the 32 ppm group measured 9.22 g (1.16 SD). Among females, the mean weight for 0 ppm was 8.60 g (1.48 SD), the 2.1 ppm group measured 8.74 g (0.99 SD), the 16 ppm group measured 8.35 g (1.37 SD) and the 32 ppm group measured 8.63 g (1.45 SD). The dot represents an outlier.
