Inferential statistics
Univariate and multivariable linear regression was used to explore the
association between RALS and independent variables at presentation (age,
sex, body mass index, BSA and RV parameters). Independent variables were
selected a priori for multivariate analyses. All clinically relevant
and/or statistically significant variables on univariate analysis with P
valeā¤0.1 were included in the multivariate analysis.
