The trend of tuberculosis incidence density rate during follow-up, among (a) patients who never started cART (N = 59) and (b) patients on cART (N = 111) in the ClinSurv HIV Cohort, Germany 2001–2011. A low number of patients who never started cART remained under observation beyond 4 years of follow-up, where no TB cases reported in the 5th, 7th, 8th, 9th and 10th years of follow-up. P < 0.001 for trend for TB incidence in patients who never started cART and patients on cART.
