    Gaps in Study Design for Immune Parameter Research for Latent Tuberculosis Infection: A Systematic Review by Mariana Herrera, Cristian Vera, Yoav Keynan, Zulma Vanessa Rueda

    Published 2020-01-01
    “…We found high heterogeneity between studies including failure to account for the time/illness of the individuals studied; varied samples and protocols; different clinical classification of TB; different laboratory methods for IP detection, which in turn leads to variable units of measurement and assay sensitivities; and selection bias regarding TST and booster effect. None of the studies adjusted the analysis for the effect of ethnicity. …”
