Table 4. Predictors of RPVO in Cohort 1, considering only the initial obstruction and fibrin properties.

Candidate predictors with p values listed in the table were incorporated in the corresponding models that had been selected by the Akaike Information Criterion to be the optimally predictive of RPVO after acute pulmonary embolism for the cohort.

Candidate predictive variables	OR (95% CI)	p*
Presentation and treatment
Initial obstruction	1.054 (1.028, 1.080)	0.00003
Fibrin property
Bβ-chain mono sialylation	1.095 (0.994, 1.206)	0.0655
Fibrin clot lysis rate	10.872 (0.349, 338)	0.1737
Fibrinogen γ’	0.614 (0.386, 0.975)	0.0388
Model goodness of fit**	0.00003

^*p value from multivariate analysis.

^**Deviance-based goodness of fit, comparing the fit of each model with the fit of the null model.
