CB, cell block; LNs, lymph nodes; NR-CB, normal saline rinse cell block method; TCC-CB, tissue coagulum clot cell block method.

a

P value for LNs: P<.001, P =.0004.

b

P value for lungs: P <.05, P =.0368.

Nondiagnostic indicates that there were no lymphocytes or alveolar cells on the CB section.
