To assess the diagnostic accuracy of galactomannan detection in BAL for the diagnosis of invasive pulmonary aspergillosis in people who are immunocompromised, at different cut-off values for test positivity, in accordance with the Cochrane Diagnostic Test Accuracy Handbook.

Our secondary objective is to study several possible sources of heterogeneity, see 'Investigations of heterogeneity'.
