CRP and isolated hemihyperplasia: Cross-sectionally, compared to reference women, IH was independently associated with low ferritin (<5th percentile, OR: 2.6, 95% CI: 1.4–4.9), high CRP (>95th percentile: OR: 1.9, 95% CI: 1.04–3.7), low hCG (<median, OR: 2.1, 95% CI: 1.40–3.16), obesity (BMI > 30, OR: 1.7, 95% CI: 1.12.9) and higher age (OR: 1.1, 95% CI: 1.04–1.15).
