Outcomes
REGRESSION
Table Multiple regression analysis was performed to explore and correct for potential interacting or confounding variables (age, sex, previous falls, FES-I at baseline, physiotherapy T0-T1 and Gait/Balance training T0-T1) in the association between group and ΔMini-BESTest, and between group and ΔFES-I. This analysis revealed that there was a significant interaction effect of age and receiving physiotherapy on the association between group and change in Mini-BESTest. Age also acted as a confounder in the relationship between group and change in FES-I. Adding these variables to the models did not result in a significant association in either model. Full regression analysis results and tables are reported in Additional file 
Outcome measures at baseline and post-interventionOutcome measures (range of possible scores) for the control- and PBT-group at T0 (baseline) and T1 (post-intervention). Change = difference between pre- and post- outcome values. Mini-BESTest = Mini Balance Evaluation Systems Test. FES-I = Falls Efficacy Score International. Increased fall risk = the percentage of participants at increased risk for falling based on their Mini-BESTest score. Data is presented as median (IQR) or n (percentage)
Mini-BESTest scores at baseline and post-intervention in the control- and PBT groups. Mini-BESTest: Mini Balance Evaluation Systems test. T0: baseline, T1: post-intervention
