Summary of DDT and DDE levels [median (IQR)] among South African women 20–30 years of age, 2010–2011, by exposure group.

Exposure group	DDT (μg/L)	DDE (μg/L)
Unsprayed villages (n = 175)	0.31 (0.11–0.86)	1.70 (0.70–5.50)
Non-DDT IRS households (n = 106)	1.40 (0.50–3.00)	7.95 (3.40–12.00)
DDT IRS households (n = 100)	2.60 (1.10–6.60)	8.50 (4.65–18.00)
The three exposure groups were statistically significantly different (p < 0.01) with regard to DDT and DDE levels, assessed using Tukey’s test for pair-wise differences.
