Level 1	The existing literature does not document the superiority of any one mesh fixation technique in relation to recurrence
Level 3	Size of the hernia (≥10 cm), body mass index (BMI) (≥30 kg/m2), history of previous open repair or failed hernia repair, and perioperative complications including SSI are risk factors for hernia recurrence irrespective of the technique
Level 3	The risk factors for recurrence include patient status, underlying disease, and perioperative factors (i.e., surgical techniques, postoperative complications, deep abscesses, and early reoperations)
Level 3	Smokers with previous failed repair attempts have a higher risk of recurrence
Level 3	Postoperative mesh infection requiring removal of mesh is a predictor of recurrence
Level 3	Higher incidence of seroma formation and recurrence are reported in cases managed with dual mesh
Level 3	Repetition of a previously inadequate technique for recurrent hernia usually fails
