Median (range) bronchoalveolar lavage fluid (BALF) and serum levels (pg/ml) of the measured cytokines and adhesion molecules in all patients (groups A + B + C) whether or not they survived

	BALF		Serum
	Survivors (n = 38)	Non-survivors (n = 27)	Survivors (n = 38)	Non-survivors (n = 27)
IL-1	215 (0–860)	410 (0–2030)	140 (3–558)	450** (3–908)
TNF-α	170 (0–2600)	222 (0–1428)	194 (94–790)	405* (60–1280)
sICAM-1	1140 (260–4620)	1520 (680–3780)	180 (66–360)	460** (66–1120)
sVCAM	312 (136–792)	356 (52–924)	150 (66–310)	380** (140–900)

^*P < 0.05, ^**P < 0.0001 versus survivors group. Comparisons were done using the Mann-Whitney test. IL-1 = interleukin-1; TNF-α = tumour necrosis factor-alpha; sICAM-1 = serumintercellular adhesion molecule-1; sVCAM = serum vascular adhesion molecule
