Analysis and data
“Do you think the study was different from what it otherwise might have been because you got a statistician involved?”
Summary
One thousand and ninety people aged 70 years or more and living at home participated in the study. The researchers summed up their findings in the British Medical Journal: A weekly exercise program focusing on balance, plus exercise at home, can help to prevent falls among Australians aged 70 years and over living at home and in good health. Home hazard management and vision screening and referral are not markedly effective in reducing falls when used alone but add value when combined with the exercise program.
Definitions of variables in data file
The data provided here is not the original data. The commitment given to study participants does not permit release of individual records. A data set has been generated with properties that are very similar to those in the original study.
| Subject | Participant number | |
|---|---|---|
| Group | 1 | Exercise, vision and home hazards interventions |
| 2 | No interventions (control group) | |
| 3 | Exercise and vision interventions | |
| 4 | Home hazards intervention | |
| 5 | Exercise and home hazards interventions | |
| 6 | Vision and home hazards interventions | |
| 7 | Vision intervention | |
| 8 | Exercise intervention | |
| Exercise | 0 = No exercise intervention, 1 = Exercise intervention | |
| Vision | 0 = No vision intervention, 1 = Vision intervention | |
| Home hazards | 0 = No home hazards intervention, 1 = Home hazards intervention | |
| Time | Time to first fall in days | |
| Censoring | 0 = Censored, 1 = Not censored (participant has had a fall) | |
