Estimated spinal canal CSA/vertebral body CSA ratio. Mean estimated spinal canal CSA/vertebral body CSA ratio in males and females at each level from L1 to L5 and overall for L1–L5 after adjusting for height and weight. All statistically significant differences are bolded. SE, standard error; CSA, cross-sectional area.
