TABLE 3.

Comparison of the overall sensitivity of the modified Wells score versus the adjusted modified Wells score for HIV/tuberculosis as additional risk factors.

Scores	MWS (95% CI)	Comparison group		Difference		McNemar’s chi-squared test p-value
		MWS & HIV only	95% CI	Difference	95% CI
MWS versus MWS + HIV only	76.66–86.43	91.02	85.36–94.63	7.69	2.86–12.51	0.0005*
MWS versus MWS + TB only	76.66–86.43	85.90	79.45–90.56	2.56	0.56–5.68	0.0455*
MWS versus MWS + HIV + TB	76.66–88.43	92.95	87.66–96.07	9.61	4.35–14.88	0.0001*

Note: MWS score - 83.33 (non adjusted for HIV/TB).

TB, tuberculosis; MWS, modified Wells score; CI, confidence interval; p-value, probability value.
