<b>Sensitivity and specificity of tuberculosis screening tools in people with diabetes</b>

This data set and data dictionary were analysed for a paper which assessed the accuracy of symptom and chest X-ray screening among people with diabetes attending routine care in South Africa. The analysis showed that symptom-based TB screening has poor sensitivity in people with diabetes. Although chest X-ray improved the sensitivity, it remained suboptimal, with a reduced specificity in people with previous TB.
