The effect of using within-patient correlation to improve shock outcome prediction
The presence of random effects shows that the shock outcome prediction accuracy can be improved by explaining more of the variation between patients, for example using the approaches outlined above, and that there is within-patient correlation between samples that should be accounted for when evaluating prediction accuracy. The specific peri-arrest factors tested here did not significantly improve prediction accuracy, but other factors should be explored.

The accuracy of such methods determines how useful it is clinically and for retrospective analysis. |
