  1. Chi-square test and Mann Whitney U test was used to establish significance among two and single categorical data groups, and results were displayed using Z and χ2 respectively
  2. OIHR Open inguinal hernia repair, LIHR Laparoscopic inguinal hernia repair, Min minutes
  3. P < 0.05 was considered statistically significant
