In the published article, there was an error in Table 3 as published. The root mean squared error (RMSE) and its interquartile range (IQR) stated as 0.93 (0.58, 0.92, 1.06) is wrong. The corrected numbers are 2.02 (0.43, 0.72, 1.24). The mean absolute error (MAE) stated for the backward elimination model states as 0.84 is wrong. The corrected number is 1.15. The corrected Table 3 and its caption “Coefficients, bootstrap inclusion frequency, and predictive performance for the backward elimination model.” appear below.
TABLE 3
| Final prediction model with backward elimination | ||
|---|---|---|
| Variable | Coefficient estimates (95% CI) on log scale | Bootstrap inclusion frequency (%) |
| Intercept | −0.67 (−1.08, −0.27) | 100 |
| Prior fall number = [1] | 0.12 (−0.32, 0.57) | 80.8 |
| Prior fall number = [2] | 0.03 (−0.50, 0.56) | 80.8 |
| Prior fall number = [3] | 0.58 (−0.10, 1.27) | 80.8 |
| Prior fall number = [4] | 0.96 (0.07, 1.85) | 80.8 |
| Prior fall number = [5+] | 1.83 (1.15, 2.52) | 80.8 |
| FES-I | 0.04 (0.02, 0.06) | 74.2 |
| theta | 0.71 (0.46, 0.95) | |
| Predictive performance | ||
| Measure | Value (IQR) | |
| RMSE | 2.02 (0.43, 0.72, 1.24) | |
| MAE | 1.15 | |
| CV RMSE | 2.17 (0.51, 0.72, 1.17) | |
| CV MAE | 1.21 | |
Coefficients, bootstrap inclusion frequency, and predictive performance for the backward elimination model.
Abbreviations: CI, confidence interval; FES-I, falls efficacy scale international; RMSE, root mean squared error; MAE, mean absolute error; IQR, interquartile range with median; CV, cross-validated.
Accoringly, a correction has been made to Results, paragraph 5. This sentence previously stated:
“The RMSE and MAE were 0.93 and 0.84, respectively; internal cross-validation increased these values to 2.17 and 1.21, respectively.”
The corrected sentence appears below:
“The RMSE and MAE were 2.02 and 1.15, respectively; internal cross-validation increased these values to 2.17 and 1.21, respectively.”
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
