↵* ± = results were considered equivocal; slightly increased uptake of 99mTc-IL-8 was seen at medial side of tibia.
TP = true-positive; C = culturing; TN = false-negative; R = radiology; FU = clinical follow-up of at least 3 mo without antibiotic treatment; S = surgery; H = histology; FN = false-negative.
