Trend of Perineal Lacerations with Incident to Subsequent Delivery. The vertical axis shows type of perineal laceration from the incident (OASIS) delivery and the horizontal axis shows the type of perineal laceration at the subsequent delivery. Each dot (subsequent vaginal delivery) or square (subsequent cesarean delivery) represents a single woman. For example, the upper left corner box shows that 5 women had a 3a laceration with their incident delivery and no lacerations with their subsequent delivery; 4/5 chose a cesarean for their subsequent delivery
