The rate ratio for exercise was 0.82 (95%
confidence interval 0.70 to 0.97, P=0.02), and a
significant effect (P < 0.05) was observed for the
combinations of interventions that involved exercise.
Balance measures improved significantly among the
exercise group. Neither home hazard management
nor treatment of poor vision showed a significant
effect. The strongest effect was observed for all three
interventions combined (rate ratio 0.67 (0.51 to 0.88,
P=0.004)), producing an estimated 14.0% reduction in
the annual fall rate. The number of people needed to
be treated to prevent one fall a year ranged from 32
for home hazard management to 7 for all three
interventions combined.
