Areal (DXA) and volumetric (HRpQCT) bone density measures, cortical microarchitectural parameters, and strength estimates (FEA) in amenorrheic athletes (AA), eumenorrheic athletes (EA) and non-athletes (NA).

Mean ± SD or Median (Interquartile Range);
†Kruskal Wallis test;
§p value reported for log converted data;
ap<0.05 after controlling for age,
bp<0.10 after controlling for age,
cp<0.05 after controlling for age and race (Black vs. non-Black),
