Propensity score matching was used to adjust for imbalances in baseline patient characteristics. The primary outcome was 1-year pragmatic hernia recurrence, defined as recurrence based on available elements of patient-reported, clinical and\/or radiographic recurrence. Secondary outcomes included 30-day surgical site infection (SSI), surgical site occurrences (SSO), surgical site occurrences requiring procedural intervention (SSOPI).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      821 patients were identified. After propensity score matching, 238 patients remained (119\u00a0MW, 119 HW). Most baseline covariates were well-matched. Patients with umbilical hernias were more likely to receive MW mesh (80% vs. 65%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=0.009), while patients receiving HW mesh were more likely to have subxiphoid hernias (5.9% vs 15%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=0.020).
