| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Hernia Recurrence | 1 Month, 3 Months, 6 Months, 12 Months, 18 Months, 24 Months, >24 Months | A recurrent hernia was defined as any hernia identified or confirmed by the investigator, during any study follow-up visit, in approximately the same position as the hernia repaired in the study procedure. Potential hernias identified via incidental magnetic resonance imaging (MRI) or computed tomography (CT) scan were evaluated by the operating surgeon for clinical significance and confirmation of hernia recurrence. |

It yields two summary measures of physical and mental health: the physical component summary (PCS) and mental component summary (MCS). The scores range from 0 to 100, where a zero score indicates the lowest level of health measured by the scales and 100 indicates the highest level of health. The change was calculated as the mean value at 24 months minus the mean value at baseline. |
