Six-month quality-of-life and functional status of acute respiratory distress syndrome survivors compared to patients at risk: a population-based study

Table 2 Mental and physical component score of SF-12 at baseline and 6 months among patients with and without ARDS

	ARDS (n = 26)	Non-ARDS (n = 41)	P value for between-patient comparison^a
SF-12 MCS baseline - mean ± SD	46.9 ± 12.4	48.9 ± 11.2	0.50
SF-12 MCS 6 months - mean ± SD	49.7 ± 12.2	51.3 ± 10.7	0.56
SF-12 MCS delta (difference in means)	2.7 (95 % CI −5.8, 5.2)	2.4 (95 % CI −5.6, 5.0)	0.9
P value for within-patient comparison^b	0.23	0.13
SF-12 PCS baseline - mean ± SD	35.7 ± 12.7	41.1 ± 13.3	0.11
SF-12 PCS 6 months - mean ± SD	32.8 ± 12.3	37.8 ± 12.3	0.11
SF-12 PCS delta (difference in means)	−3 (95 % CI −6.1, 5.5)	−3.3 (95 % CI −6.1, 5.4)	0.9
