Representation of the discriminatory power of Aspergillus GM-EIA (a) and BAL (b) when combining these with chest CT. a CT⁺-GM⁺; episodes proved to be positive when testing both by CT and Aspergillus GM-EIA, CT⁺-GM⁻; episodes proved to be positive when scanning by CT and negative when testing by Aspergillus GM-EIA, CT⁻-GM⁺; episodes proved to be negative when scanning by CT and positive when testing by Aspergillus GM-EIA, PCR⁻-GM⁻; episodes proved to be negative when testing by both CT and Aspergillus GM-EIA. Black symbols represent controls while red symbols represent cases. Contoured symbols represent episodes with ceased fever, while shaded symbols represent episodes with present or recurrent fever refractory to broad spectrum antibiotic treatment. Small sized symbols represent children. Numbers denote patient ID numbers. b CT⁺-BAL⁺; episodes proved to be positive when testing both by CT scanning and BAL, CT⁺-BAL⁻; episodes proved to be positive when testing by thoracic CT and negative when testing by BAL, CT⁻-BAL⁺; episodes proved to be negative when testing by thoracic CT and positive when testing by BAL, CT⁻-BAL⁻; episodes proved to be negative when testing both by thoracic CT and BAL. Black colored symbols represent controls while red colored symbols represent cases. Contoured symbols represent episodes with ceased fever, while shaded symbols represent episodes with present or recurrent fever refractory to broad spectrum antibiotic treatment. Small sized symbols represent children. Numbers denote patient ID numbers
