The validity of the proposed polynomial equation was assessed by the values of (R^{2}), (R_{text{Adj}}^{2}) and (R_{text{Pred}}^{2}).
The effect of the corrosive environment on crack growth rates and on the coefficients of the Paris equation were assessed for each type of electrode.
Finally, the validity and the robustness of the model and predictive equation were assessed by statistical tests (Figure 1, step 4).
The adequacy of the derived model equation was assessed by standard goodness-of-fit procedures.
The calibration of the prediction equation was assessed by comparing the observed and expected numbers of 30-day mortality.
The calibration of the prediction equation was assessed by comparing the observed and expected numbers of 90-day mortality or complicated hospitalization rate by decile of predicted risk.
Complaints, quality of life and parameters related to the energy balance equation are assessed with an online questionnaire children or parents fill out at home.
The calibration of the prediction equation was assessed by comparing the observed and expected numbers of 90-day mortality or complicated hospitalization.
The Australasian SAPS III equation was assessed in the entire population, but we only extracted data from the development cohort for comparison with SAPS III general equation data on calibration and SMR.
The agreements between the gold standard Cr-EDTA infusion clearance method and the urinary CrCl method, as well as the estimating equations used for eGFR (the CG equation, the MDRD equation and the CKD-EPI equation), were assessed according to Bland and Altman [ 16].
