Values are expressed as absolute frequency (percentage) for categorical variables and as median (interquartile range) for continuous variables. Chi-squared test for categorical variables; Kruskal–Wallis test for continuous variables. 1Mild complications: hematoma, seroma, cutaneous necrosis, early infection, abdominal or lumbar pain, liponecrosis, and volume loss. Severe complications: late infection, capsular contraction, implant exposure, implant rupture, hernia, flap necrosis, bulging, and microvascular complications requiring surgery. 2Microvascular complication requiring surgery.
