However, because CD4 cell count was significantly lower in the active TB group compared to the other two groups, we were concerned that differences in CD4 count confounded the relationship between soluble inflammatory markers and active TB.

The authors concluded that "[t]his raises the concern that differences in mortality between centres may be partly due to variation in physicians' perceptions of long-term prognosis" [ 26].
