Conversely, the rate of OASIS (third or fourth degree perineal tears) was lower with marginal significance in the research group compared to controls in univariable analysis (2 (0.5%) versus 15 (2.0%), respectively, p = 0.057) and became statistically significant after controlling for the confounders mentioned above (aOR 0.1 95% CI 0.02–0.52).
