Level 2b	Among common methods of measuring abdominal wall hernia defect, sizes are only weakly to moderately correlated
Level 2a	Large defect widths and total area have a greater chance of pain and activity limitation at 1-month follow-up, but not long term
Level 3	Dynamic rather than static measurements of ventral hernia area during laparoscopy provide a simple way of in vivo objective measurement that helps the surgeon choose the appropriate size of mesh
Level 1	Despite the ability to characterize ventral hernia morphology and recurrence with precision, most indexed studies do not employ imaging
