Proportion of tuberculosis attributable to diabetes in the subpopulation of people with diabetes

	Attributable Fraction (Exposed)
	Total pulmonary tuberculosis %(upper and lower bounds)		Smear-positive tuberculosis % (upper and lower bounds)
Overall	80.5	(39.9 – 93.7)	85.9	(65.9 – 94.2)
Age in years
25–29	87.2	(15.3 – 98.1)	84.9*	(39.4 – 96.2)
30–39	90.0	(85.4 – 93.1)	84.9*	(39.4 – 96.2)
40–49	78.8	(72.1 – 83.9)	92.1	(86.6 – 95.4)
50–59	56.5	(45.4 – 65.5)	80.7	(67.4 – 88.5)
60+	43.2	(6.5 – 65.6)	74.7	(27.5 – 91.2)

*As no relative risk (RR) was available for smear-positive tuberculosis incidence for the age band 25–29, the RR for the age band 30–39 was used.
