Studies that specified how many patients were coinfected with HIV.

AuthorYearCountryTotal patientsPercent HIV positiveFindings

Madhi et al. [31]1999South Africa13040%Did not attempt to validate scoring criteria

Kiwanuka et al. [42]2001Malawi11071% (of 102 tested)Did not attempt to validate scoring criteria

Palme et al. [39]2002Ethiopia51711.2%Did not attempt to validate scoring criteria

van Rheenen [18]2002Zambia14730%Keith Edwards scoring system: sensitivity 88% and specificity 25% in this study. Most of the children with a false positive score were malnourished (48%) or had AIDS (31%)

Marais et al. [26]2006South Africa4288.8%Sensitivity, specificity, and PPV all decreased significantly when HIV infected children included

Edwards et al. [47]2007Democratic Republic
of Congo
9146%Out of 8 scoring systems analyzed, 3/8 systems did not recommend treatment in 14% of HIV-infected children compared to 2% of noninfected children. Mean score tended to be higher for HIV-infected children, but only significant for Edwards score

Viani et al. [8]2008Mexico13100%Applied Stegen-Toledo criteria retrospectively but without culture results: 77% had highly probable TB, 15% probable, and 8% suspicion of TB

Pedrozo et al. [23]2009Brazil2395%Analyzed scoring system by looking at median scores of various groups: median score of 3a (TB+, HIV−) and 3b (TB+, HIV+) sig. higher than TB negative groups, median score of TB+ groups also was higher than the cutoff of 30

PPV: positive predictive value.
