Statistical Analysis
Statistical analysis was performed with the online medical statistics application EasyMedStat (version 3.17; www.easymedstat.com). The data presented as mean with standard deviation, and categorical variables were shown as percentages. A multivariate logistic regression was performed to assess the relation between falls and ACB score, CCI and age. Odds ratio was adjusted for different sets of confounders and are reported with 95% confidence intervals. Data were checked for multicollinearity with the Belsley-Kuh-Welsch technique. Heteroskedasticity and normality of residuals were assessed respectively by the White test and the Shapiro-Wilk test. A p-value < 0ยท05 was considered statistically significant.
