Post-test probability of tuberculous pleural effusion according to pre-test probability*

 Post-test probability Pre-test probability 10% 25% 50% With positive result (%) 76.7 (45.1 to 92.9) 90.8 (71.2 to 97.5) 96.8 (88.2 to 99.2) With negative result (%) 0.009 (0.006 to 0.013) 0.025 (0.017 to 0.038) 0.074 (0.048 to 0.107)
• *Values in parentheses are 95% CIs estimated by using the lower and upper CIs of the random-effects weighted detection rate and false-positive rate estimates.
