Changes in the SUVmax of the parietal bone with the duration of bisphosphonate administration. (a) The scatter plot of SUVmax of the parietal bone versus duration of bisphosphonate administration for all diseases showed a positive correlation between the two variates (rs = 0.65, P = 0.0002). The correlation line equation and the coefficient of determination were: Y = 0.014 X + 1.154, R2 = 0.427. (b) The scatter plot of the SUVmax of the parietal bone versus duration of bisphosphonate administration for all diseases, after excluding four patients with bone metastasis treated with intravenous bisphosphonate, showed a positive correlation between the two variates (rs = 0.62, P = 0.0009). The correlation line equation and the coefficient of determination were: Y = 0.0152 X + 1.150, R2 = 0.459.
