Sex	0.037	0.209 (0.048–0.097)	0.014	0.153 (0.034–0.685)
Portal vein velocity	0.026	1.067 (1.008–1.131)	0.021	1.075 (1.011–1.143)
PT (normal/abnormal)	0.048	2.087 (1.008–4.322)	0.260	1.254 (0.533–2.951)

Mean	0.017	0.967 (0.941–0.994)	0.237	0.973 (0.954–1.012)

Abnormal PT: PT>14 s; abnormal NEUT#: NEUT#<1.80 or >6.40 × 10⁹/L.

Bold values indicate statistical significance if P < 0.05.

CI, confidence interval; mean, average of relative strain; NEUT#, neutrophil absolute value; OR, odds ratio; PT, prothrombin time.
