Figure 1. Annual Change in Bone Mineral Density (BMD) by Menopausal Status.

Figure 1.

Circles represent mean annual change, comparing BMD in grams per centimeter squared at baseline with follow-up. Whiskers represent 95% CIs. Only women with serial BMD measurements are included in the subgroup analysis. Sample sizes for each comparison are outlined in Table 3. P values compare mean percentage change in BMD by menopausal status and were derived using the t test for 2 independent samples.

aP < .001.

bP = .006.
