Table 3. Overview of PD-L1 expression on immune cells and MPM tumor cells in eleven different MPM fluid samples.

		DCs	B CELLS	MACROPHAGES	TUMOR CELLS
Pleural fluid
PD-L1	Positive samples (%)	6/6	4/6	5/6	5/6
	ΔMFI rangeMIN-MAX	305–749	9–1684	128–972	20–14524
Ascites fluid
PD-L1	Positive samples (%)	5/5	5/5	5/5	5/5
	ΔMFI rangeMIN-MAX	159–1296	10–477	331–1801	955–2679

Variation in the intensity of expression is shown by the range of ΔMFI values. MFI, Mean Fluorescence Intensity.
