Analyses based on 473 women (excluding 26 without diagnoses) in the operative and 127 women (excluding 4 without diagnoses) in the population samples. Concentrations were log (x + 1) transformed for analysis; results are per logarithm unit change.
a
Adjusted for age (years) and body mass index (continuous).
b
Adjusted for age (years), body mass index (continuous), and parity conditional on gravidity (never pregnant, pregnant without births, pregnant with births).
