Association between blood heavy metals exposure with uterine fibroids among American women: a cross-sectional analysis from NHANES data

Table 2 Blood cd, pb, and hg differences between group with or without uterine fibroids

Heavy metals	Total(n = 4502)	With Uterine Fibroids (n = 542)	Without Uterine Fibroids (n = 3960)
Blood Pb, (µmol/l)	0.048(0.034,0.072)	0.053(0.041,0.082)	0.048(0.034,0.071)
Blood Cd, (nmol/l)	3.560(1.780,5.340)	3.560(2.580,5.870)	3.560(1.780,5.340)
Blood Hg, (µmol/l)	4.740(2.500,8.980)	5.990(3.490,10.980)	4.490(2.500, 8.880)

This table presents the median and interquartile range (25th and 75th percentiles) of blood heavy metal concentrations (Pb, Cd, and Hg) among all participants. The statistical comparisons were performed using the Wilcoxon rank-sum test, which is appropriate for non-normally distributed data
