Statistical analysis

Continuous variables are presented as mean ± standard deviation (SD), and categorical variables are presented as absolute numbers and percentages. The correlation between SUVmax of histologically proven metastatic sites and SUVmax of the detected primary sites was determined using Pearson’s correlation coefficient and P<0.05 were considered as statistically significant. Microsoft Office Excel 2007 and MedCalc commercial software package (MedCalc Statistical software version 14.12.0–32 bit, Belgium) (31) were used for all the statistical analyses and preparing data sheets.
