Addition of HbA1c content improved GRACE score alone model discrimination, which was confirmed by the IDI and the continuous, category-free NRI (>0).
The reference and new AKI risk prediction models were compared by the continuous (category-free) net reclassification improvement (NRI) and integrated discrimination improvement statistics [ 19- 21] and difference in AUC [ 22].
For analysis, some independent variables were dichotomized (sex, current smoking, alcohol use, physical activity, asthma, diabetes, obesity, disability); others with multiple or continuous response categories (age, race/Hispanic ethnicity, income, and employment status) were reduced to the smallest number of meaningful categories yielding at least 5 cases or more in any table cell.
Based on previous studies [ 36], five continuous offense categories were created.
Weight z scores and BMI z scores over time (continuous and categories) were entered into their respective parametric survival model as time-dependent covariates.
For clinico-pathological features that grouped tumours into three or more continuous, unpaired categories, a Kruskal-Wallis test was used to assess association.
Then, three classical kinetic models are combined to analyze the superfine coal pyrolysis process, including Coats-Redfern (model-fitting type), Starink (model-free group) and distributed activation energy model (DAEM, continuous distribution category).
In the case-control study, we performed the logistic regression analysis for the association between the risk scores and T2DM and IGR in both continuous and category patterns (Table 4).
The mean (SD) is given for continuous variables; category variables are given in terms of absolute frequencies and percentages; and ordinal variables (Apgar) in terms of the median (min-max).
The final ANOVA revealed that for two electrodes, CP1 and F4, there was a time window 144 171 msec, where a continuous Response Category × Subject Status interaction was found to be significant.
