Graphs showing expected vs observed perception of health at 6 and 12 months in the ALTOS and ICAP cohorts. Perception of health was evaluated using the EQ-5D-VAS questionnaire. Expected perceptions of health estimated using patient responses to 35 questions from the 36-item Short Form Health Survey version 2 and EQ-5D-VAS about physical functioning, social functioning, mental health, bodily pain, role limitations resulting from physical health or emotional problems, vitality, energy, and fatigue. Areas of the plot shaded red indicate that the survivor’s perception of his or her health was > 8 points better than predicted, corresponding to positive perception deviation. Areas of the plot shaded blue indicate that the survivor’s perception of his or her health was > 8 points worse than predicted, corresponding to negative perception deviation. Pearson correlation coefficients reported. P < .001 for the test of the null hypothesis, and r = 0 in both cohorts at both time points. ALTOS = ARDSNet Long Term Outcomes Study; ICAP = Improving Care of Acute Lung Injury Patients study; PD = perception deviation; VAS = visual analog scale.
