The nature of the effusion was mucoid (M) in 19 MEE samples, seromucous (SM) in four and mucopurulent (MP) in one MEE sample.
†
Duration of the effusion (months).
‡
TCC (SC5b-9) levels were measured by a neoepitope-specific EIA.
§
Semiquantitative estimation (band intensity) of CD59 in the MEE samples by immunoblotting: + + + = strong, + + = moderate, + = weak, - = no CD59 detected and n.d. = not done. Due to the limited amount of MEE not all determinations could be carried out from all samples.
