Table 2

Frequency of the different Hp phenotypes in normal and high e-PASP groups.

Hp phenotype	Normal e-PASP (e-PASP <35 mmHg) % ()	High e-PASP (e-PASP ≥35 mmHg) % ()	value
Hp 1-1	16.7 (11)	3.6 (2)	0.019
Hp 2-1	31.8 (21)	42.9 (24)	0.208
Hp 2-2	51.5 (34)	53.6 (30)	0.818
Total	100 (66)	100 (56)

= 0.019 comparing the prevalence of Hp 1-1 phenotype in normal e-PASP group versus the high e-PASP group.
