Imputation process, in order of execution, for each of the datasets in the integrated dataset
| Imputation step | Model inputs | Imputed variable output | |||
|---|---|---|---|---|---|
| Datasets | Variables | Dataset | Variable | Number of samples imputed | |
| 1 | 5 | Age, gender, cytology, FISH, Cxbladder Detect | 5 | NMP22 | 2 |
| 2 | 5 | Age, gender, NMP22, FISH, Cxbladder Detect | 5 | Cytology | 3 |
| 3 | 1, 4, 5 | Age, gender, cytology, NMP22 | 4 | Cxbladder Detect | 193 |
| 4 | 1, 2, 3, 4, 5 | Age, gender, cytology, Cxbladder Detect | 2 | NMP22 | 80 |
| 3 | NMP22 | 80 | |||
| 5 | 3, 4, 5 | Age, gender, cytology, Cxbladder Detect | 3 | FISH | 68 |
| 6 | 2, 4, 5 | Age, gender, cytology, Cxbladder Detect | 2 | FISH | 80 |
| 7 | 1, 4, 5 | Age, gender, cytology, Cxbladder Detect | 1 | FISH | 474 |
Note: all imputations maintain at least a 70 % level of known data
