Systematic Review: T-Cell–based Assays for the Diagnosis of Latent Tuberculosis Infection: An Update
Figure 1.Forest plot of studies estimating sensitivity of interferon-γ–release assays in patients with active tuberculosis as a surrogate
for latent tuberculous infection.
Point estimates for sensitivity and 95% CIs are shown along with pooled estimates. Top. QuantiFERON-TB Gold (16 studies). Middle. QuantiFERON-TB Gold In-Tube (6 studies). Bottom. T-SPOT.TB (13 studies).
