- Abbreviations; partial pressure of carbon dioxide (PCO2), oxygen pressure in the blood (PO2), Bicarbonate (HCO3), International Normalized Ratio (INR), B represents the unstandardized coefficient, which indicates the change in the dependent variable (prognostic CPR duration) associated with a one-unit change in the corresponding independent variable (laboratory test). Std. Error refers to the standard error of the coefficient estimate. Beta represents the standardized coefficient, reflecting the standardized effect size of each laboratory test on the CPR duration. t represents the t-value, which tests the significance of the coefficient estimate. P-value indicates the level of statistical significance for each laboratory test’s contribution to the linear regression model
