ZN: Ziehl–Neelsen microscopy; LED-FM: light-emitting diode fluorescence microscopy. Bold indicates key measures. #: two sputum samples were collected from each individual; ¶: samples from LED-FM+ but ZN− individuals; +: percentages indicate how many samples were indicated by rats and would be evaluated by LED-FM.
