Table 3. Likelihood ratio for indeterminate results based on the combination of lymphocyte count and NLR in 2773 QuantiFERON-TB Gold In-Tube (QFT-GIT) tests.

	Determinate	Indeterminate	Likelihood ratio
	(n)	(n)	(95% CI)
NLR (≥5.18) and Lymphocyte (≤1050/μL)	324	80	2.81 (2.30–3.45)
NLR (≥5.18) and Lymphocyte (≥1051/μL)	233	52	2.54 (1.95–3.32)
NLR (≤5.17) and Lymphocyte (≤1050/μL)	265	20	0.86 (0.56–1.33)
NLR (≤5.17) and Lymphocyte (≥1051/μL)	1729	72	0.47 (0.39–0.58)

Positive and negative results of QFT-GIT are considered as “determinate”.
