Figure 1. Probability of having a PE is associated with low clinical and QOL assessments.

Figure 1

Using the Kaplan-Meier survival analysis, we evaluated whether the markers were associated with the risk of a PE. Continuous covariates were dichotomized at the median. The parameters illustrated here were all influencing the probability of having a PE. Lower risks of PE were associated with A) higher FEV1% predicted (p = 0.020), B) higher FVC% predicted (p = 0.032), C) higher Clinical subscore of the Matouk Disease Score (p = 0.004), D) lower Complications subscore of the Matouk Disease Score (p = 0.000), E) higher assessments of QOL physical (p = 0.030) and F) higher health perceptions (p = 0.006) domains.
