↵* Values in parentheses represent percentages of patients in each BMI group with positive detection of hot nodes.
↵† McNemar analysis was used for comparison of detection of hot nodes by planar imaging and detection of hot nodes by SPECT/CT. Data for patients with BMI values of less than 18.4 and 18.5−24.9 (normal weight) were analyzed together.
