Figure 4.

The y-axis represents the predicted probability of all-cause mortality ranging from 4% (shown in dark blue), 5% to 10% (shown in purple), 10% to 15% (shown in blue), 15% to 20% (shown in green), 20% to 25% (shown in orange), 25% to 30% (shown in yellow), 30% to 35% (shown in red), to > 35% (shown in dark red) for each decile of loading score for factors 1 (Emphysema Axis) and 2 (Airway Axis) in a Cox proportional hazards model including age, sex, current smoking, pack years of smoking, BMI, high BP, each of the five factors, the interaction between factors 1 and 2, and a quadratic term for factor 2. The x and z axes represent deciles of each axis, ranging from 1 (representing a small loading score) to 10 (representing a large loading score).
