PPV (%)	91.18	94.59	0.574
False-positive rate (%)	27.27	18.18	—
False-negative rate (%)	18.42	7.89	—
Positive likelihood ratio	2.99	5.07	—
Negative likelihood ratio	0.25	0.10	—

Sensitivity, specificity, PPV, and NPV were used to compare the diagnostic value of the PAS and GMS of LCT in BAL fluid. IPA: invasive pulmonary aspergillosis; PAS: periodic acid-Schiff; GMS: Grocott’s methenamine sliver; LCT: liquid-based cytopathology test; BAL: bronchoalveolar lavage; NPV: negative predictive values; PPV: positive predictive value.
