No. of PF CFP-10 SFU (ISL)	56	57 (912)	Not done	Not done	>400 (>1,852)
PF/blood ratio of no. of ESAT-6/10e6 lymphocytes	8.57c	1.03	Not done	Not done	>109
PF/blood ratio of no. of CFP-10/10e6 lymphocytes	7.00c	1.22	Not done	Not done	>44

^aPF = pericardial fluid, TB = tuberculosis, SFU = spot-forming units, ISL = number of IFN-γ-secreting lymphocytes/10e6 lymphocytes in pericardial fluid, ZN = Ziehl-Neelsen.

^bWe considered 400 SFU as the maximum discernible number of SFU.

^cRatio shown in SFU.
