Chest Х-ray in patients with PAH and CTEPH.

Parameters	Patient groups						Upper limit of normal value
	PAH	IPAH	PAH-CTD	PAH-CHD	PoPH	CTEPH
Diameter of the right PA root (cm)	1.9 [1.6; 2.6]	2.0 [1.7; 2.3]	1.7 [1.6; 1.9]^1.3	2.1 (1.7; 2.6)	1.8 [1.6; 2.2]	1.8 [1.6; 2.3]	≤1.5
Moore’s coefficient (%)	35.9 [32; 41]	36.2 [33; 38]^2.4.5	35.7 [32; 39]^3	39.7 [35; 43]^5	33.4 [31; 35]	34.0 [30.0; 38.0]	≤30
Lupi’s coefficient (%)	35.6 [32; 39]	35.1 [33; 38]	34.6 [32; 36]^3	38.6 [36; 42]^4.5	34.6 [32; 36]	35.0 [33.0; 37.0]	≤33
Cardiothoracic ratio (%)	51.7 [45; 57]	51.8 [48; 55]	50.5 [48; 53]	53.5 [38; 64]^5	49.3 [43; 51]	51.0 [48; 57.0]	≤50

Note: : at the time of diagnosis; 1: ; 2: ; 3: ; 4: vs. ; 5: vs. . Moore’s coefficient: percentage of the distance from the farthest point of the PA arc to the vertebral midline to the half chest diameter. Lupi’s coefficient: the percentage of the sum of the distances from the midline to the first division of the right and left pulmonary arteries to the diameter of the chest.
