aThe proportions of TB survey cases with known HIV status and notified TB cases that were HIV-positive, respectively, were as follows: Kenya (0.17, 0.31), Malawi (0.28, 0.55), Rwanda (0.03, 0.26), Tanzania (0.08, 0.37), Uganda (0.27, 0.44), Zambia (0.27, 0.61) and Zimbabwe (0.51, 0.69). The size of the best estimate (black square) is proportional to the model’s weights (inverse variance).
b Bacteriologically-confirmed TB cases could not be verified for Tanzania, so the value for smear-positive TB is shown instead.
