GSTM1 and tuberculosis: As an indicator of inflammation severity (30), serum albumin levels were found to be significantly lower in mod-sev TB (p=0.0007) and anemic TB patients (p=0.001) (Figures 1J, K), and there was a positive correlation (r=0.38; p<0.0001) between blood Hb and serum albumin levels in all TB patients (Figure 1M).
