Impact of Hemodialysis on Dyspnea and Lung Function in End Stage Kidney Disease Patients

Figure 3

Box plot showing the relationship of (Δ) mMRC with (Δ) 𝑃_0.1 before and after hemodialysis. Dashed line: regression line. Solid lines: median lines of the change (Δ) of 𝑃_0.1 at ΔmMRC values of 1 and 2, respectively. Regression equation: 𝑦=−0.736+(0.905∗𝑥)±2(0.44), 𝑛=25, 𝑟=0.71, and 𝑃<0.001. The slope of the line indicates that the (Δ) mMRC decreases, on average, by one unit per 0.9 units decrease of the (Δ) 𝑃_0.1.
