wsSUVmax = whole-skeleton SUV_max; wsSUVmean = whole-skeleton SUV_mean; ALP = alkaline phosphatase; VM = visceral metastases; IDC = invasive ductal carcinoma; ILC = invasive lobular carcinoma.
* Calculated using Lausen test.
↵^†Calculated using log rank test.
↵^‡In relation to 2 groups compared (excluding missing data and other groups).
^§Variables selected for multivariate analysis (P ≤ 0.1).
Variables were divided into 2 groups for OS comparison. Numbers of individuals in group 1, and P values of difference in OS between 2 groups, are also presented.
