Comparative performance outcomes of the clinical prediction rule, LAM, and a combination of LAM and the clinical prediction rule for the diagnosis of definite TB meningitis.

*One patient did not have lymphocyte count and was excluded.†Clinical prediction rule.‡p value comparing sensitivity of the clinical prediction rule alone (47%) vs. the clinical prediction rule plus the LAM result (63%) = 0.07.#p value comparing sensitivity LAM 31% vs. clinical prediction rule combined with LAM (63%) Sens = sensitivity, Spec = specificity, PPV = positive predictive value, NPV = negative predictive value.
