fall-prone individuals in stroke rehabilitation.Based on
a multiple Cox regression model, this index summarizes
the presence of 8 risk indicators (Table 1).
To evaluate the usefulness and accuracy of the prediction
that any regression model gives, cross-validation
studies should be applied to a second sample. Predictor
variables found to be important for 1 sample would not
necessarily be accurate for another sample,owing to
chance variations in the correlations between variables.
The sample selection and sample size may also influence
which variables will be selected for the model. The purpose
of this study was therefore to validate the predictive
accuracy of the fall risk index using a new sample of
stroke patients.
