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

Figure 4

(a) Relationship of (Δ) Wt with the (Δ) CV % pred. Solid line: regression line. Regression equation: 𝑦=1.874−0.0145∗𝑥±2(0.195), 𝑛=23, 𝑟=0.65, 𝑃<0.001. Subjects, represented as black dots, are 23 because closing volume could not be calculated in 2 patients. (b) Relationship of the (Δ) Wt to (Δ) 𝑃_𝑖max % pred. Solid line: regression line. Regression equation: 𝑦=4.064−(0.0424∗𝑥)±2(0.581), 𝑛=25, 𝑟=0.533, and 𝑃=0.006. The 25 subjects are represented as black dots.
