Table 3.

Comparison between pleural cytopathology results and FDG-PET scan results; atypical or reactive cytopathologies were not included.

	Pleural Cytopathology Positive	Pleural Cytopathology Negative (Excludes Atypical or Reactive Cytology)
FDG-PET Positive	58	7
FDG-PET Negative	12	8

FDG-PET uptake and positive cytopathology: sensitivity, 82.9%; specificity, 53.3%. Positive predictive Value: 89.2%; 95% CI: 82.7–93.5%. Negative predictive value: 40.00%; 95% CI: 24.8–57.3%. Positive likelihood ratio: 1.78; 1.02–3.08. Negative likelihood ratio: 0.32; 0.16–0.65. Fisher’s exact test: p = 0.0057.
