Average sensitivities and specificities calculations across 50 data imputations

Model 2	Model 1			Model 2
	Average	Maximum	Minimum	Average	Maximum	Minimum
Specificity	85.3	85.7	84.8	85.6	86.2	85.2
Sensitivity	54.3	55.4	53.6	54.6	55.4	54.1
Overall correct classification	73.9	74.2	73.5	74.8	74.9	74.5

NOTE. Model 1 examined the prediction of falls from the TUG test, adjusting for all study covariates, whereas model 2 examined whether the effect of the TUG test was invariant across H&Y levels (ie, an H&Y × TUG interaction was also included). The overall correct classification represents the percentage of the sample whose fall status was correctly classified.

Abbreviations: Sensitivity, percentage of fallers who were correctly identified; specificity, percentage of nonfallers who were correctly identified.
