A comparison of antigen-specific T cell responses induced by six novel tuberculosis vaccine candidates - Fig 3

Vaccine-induced memory CD4 (A) and CD8 (B) T cell responses by vaccine and M.tb infection status. Frequencies of antigen-specific Th1-cytokine expressing CD4 (a) or CD8 (B) responses at the final time point in each trial, relative to the pre-vaccination frequencies (i.e. memory response minus pre-vaccination response). Points denote sample trimmed means, and error bars 95% CI. Solid error bar lines indicate responses that significantly exceeded 0% after controlling the false discovery rate at 0.01. Dashed lines did not meet this significance criterion.
