Geometric mean of blood lead levels. For people on a GFD, the geometric mean of blood lead is greater in men and women than for people not on a GFD. However, the significant differences were found only in women (P = .001). *P = .001, **P = Error bars indicate 95% confidence interval.

Geometric mean of blood cadmium levels. Compared with people not on a GFD, the geometric mean of blood cadmium level of people on a GFD is greater in nonsmokers (0.33 [95% CI, 0.28–0.38] vs 0.25 [95% CI, 0.24–0.25]) and ex-smokers (0.49 [95% CI, 0.43–0.57] vs 0.33 [95% CI, 0.32–0.34]). *P = .001, **P < Error bars indicate 95% confidence interval.
