Data Key:

1. SDA (Van der Pol, 2001): Asymptomatic—Sensitivity = 100%, Specificity = 99.5%
2. SDA (Van der Pol, 2001): Symptomatic—Sensitivity = 98.4%, Specificity = 94.8%
3. Culture (Crotchfelt, 1997): Sensitivity = 76.6, Specificity = 100%
4. PCR (Martin, 2000): Asymptomatic—Sensitivity = 73.1%, Specificity = 99.0%
5. PCR (Martin, 2000): Symptomatic—Sensitivity = 98.1%, Specificity = 98.8%
6. PCR (Van Doornum, 2001): Sensitivity = 100%, Specificity = 99.2%
7. PCR (Crotchfelt, 1997): Sensitivity = 97.3%, Specificity = 97.0%
