|
Mycobacterium tuberculosis M72-specific antibody geometric mean concentrations (GMCs) with exact 95% Confidence Interval (CI) were measured by Enzyme Linked Immuno Sorbent Assay (ELISA) and expressed in ELISA unit per milliliter (EU/mL).
The cut-off of the assay was 2.8 EU/mL.
The Geometric Mean Concentration (GMC) calculations were performed by taking the anti-log of the mean of the log10 concentration transformations.
For descriptive statistics purposes only, antibody concentrations below the cut-off value of the assay was given an arbitrary value of half the cut-off value for the purpose of GMC calculation.
