From: Analysis of low-dose estrogen on callus BMD as measured by pQCT in postmenopausal women
Shows scatterplots representing measurements of the CALCBD content (a1 and b1) as well as the cortical bone density (CORTBD) (a2 and b2) of the healthy arm (a1 and a2) compared to the fractured arm at the height of the fracture gap of the radius (see b1 and b2); the scatterplots represent the measurements with (right side) and without treatment (left side) of estrogen. a1: shows total CALCBD levels of the healthy side of individual patients of different ages with bone fractures on the opposite side. a2: shows the CORTBD density measurements during bone healing. b1: shows total CALCBD levels of the fracture gap of individual patients of different ages. b2: shows CORTBD density in the fracture gap. The gray shading shows the 95% confidence interval. n (E2) = 31; n (placebo) = 45. R2 represents the coefficient of determination; r represents the correlation coefficient
