(A and B). Plasma was used to perform ELISA using the Human BCG antibody ELISA kit. Two replicates of each sample were used for both case and control samples. The number of samples (n) for cases and controls at V0 was 19/15; at V1, n = 15/15; at V2, n = 12/8; and at V3, n = 8/3 respectively. Statistical differences were determined using mixed effects analysis and Tukey’s multiple comparison tests. Statistical significance was determined at p < 0.05 and a 95% confidence level. * Implies a p-value less than 0.05
