Assessment of the quality of data
| Steps for interpretation | Interpretation by Robson | Example: MCS population | Our findings | Additional information from the database used to interpret data | Final interpretation |
| STEP 1. Total number of CS and total number of women delivered | Should be identical to the numbers provided by official register | NA | Total CS=2251 Total deliveries=7504 | – | There are no missing/incorrect data |
| STEP 2. Size of group 9 (should be less than 1%) | <1% | 0.4% | 0.9% | – | No significant misclassification for this group according to references by Robson |
| STEP 3. CS in group 9 (should be 100% by convention) | 100% | 88.6% | 72.3% | – | Misclassification |
