Flowchart showing recruitment and follow-up of participants with Parkinson disease (PD).
Receiver operating characteristic (ROC) curves for the Berg Balance Scale (BBS), Dynamic Gait Index (DGI), Functional Reach Test (FRT), Falls Efficacy Scale–International (FES-I), Activities-specific Balance Confidence Scale (ABC), and Timed “Up & Go” Test (TUG). AUC=area under the curve, CI=confidence interval.

Analysis of Individual Self-Report and Performance-Based Balance Measures for the 12-Month Follow-up Perioda
↵a AIC=Akaike information criterion, AUC=area under the curve, CI=confidence interval, LR+=likelihood ratio for a positive test result, LR−=likelihood ratio for a negative test result, BBS=Berg Balance Scale, DGI=Dynamic Gait Index, FRT=Functional Reach Test, FES-I=Falls Efficacy Scale–International, TUG=Timed “Up & Go” Test, ABC=Activities-specific Balance Confidence Scale, BESTest=Balance Evaluation Systems Test, N/A=not applicable, Mini-BESTest=condensed version of the BESTest, FGA=Functional Gait Assessment, Brief-BESTest=shortened version of the BESTest.
b The pretest probability of being a recurrent faller was 32.5%.61,62 Data were from previous prospective studies and include values for a 6-month follow-up period.
c “63%” and “46%” were defined by Duncan et al as “percentage score determined from raw score to ease comparison to the BESTest.”61(p548)
d Confidence intervals were not reported.
Analysis of Two-Test Modelsa
↵a AIC=Akaike information criterion, CI=confidence interval, LR+=likelihood ratio for a positive test result, LR−=likelihood ratio for a negative test result, FES-I=Falls Efficacy Scale–International, BBS=Berg Balance Scale, DGI=Dynamic Gait Index, TUG=Timed “Up & Go” Test, ABC=Activities-specific Balance Confidence Scale, FRT=Functional Reach Test.
b Number of people with positive test result in each condition.
Analysis of Three-Test Modelsa
↵a AIC=Akaike information criterion, CI=confidence interval, LR+=likelihood ratio for a positive test result, LR−=likelihood ratio for a negative test result, FES-I=Falls Efficacy Scale–International, BBS=Berg Balance Scale, DGI=Dynamic Gait Index, TUG=Timed “Up & Go” Test, FRT=Functional Reach Test, ABC=Activities-specific Balance Confidence Scale.
b Number of people with positive test result in each condition.
Demographic and Disease-Specific Characteristics and Balance-Related Measures for Recurrent Fallers and Nonrecurrent Fallersa
↵a Participants were classified as recurrent fallers if they reported 2 or more falls in the 12-month follow-up period and as nonrecurrent fallers if they reported no fall or 1 fall. CI=confidence interval, LED=levodopa equivalent dose, UPDRS=Unified Parkinson Disease Rating Scale, ADL=activities of daily living, BBS=Berg Balance Scale, DGI=Dynamic Gait Index, FRT=Functional Reach Test, ABC=Activities-specific Balance Confidence Scale, FES-I=Falls Efficacy Scale–International, H&Y=modified Hoehn and Yahr stage, TUG=Timed “Up & Go” Test.
b Values are reported as mean (SD) unless otherwise indicated.
c Pearson chi-square test.
d t test.
e Mann-Whitney U test.
