Effectiveness: patients without failure or complications over time
The rate of patients without failure over time according to each surgical strategy is presented in Figure 2. Hysterectomy was the most effective strategy, as the rate of patients without failure was the highest over time, attaining 97.2% at 18 months and remaining stable until 60 months (Table 2). Conversely, the rate of patients without failure for 2G, 1G and curettage, being 90.1%, 87.3% and 79.4% at 18 months (p<0.0001), showed decrease over time.
The rate of patients without complication over time according to each surgical group is presented in Figure 3. Women undergoing hysterectomy were at significantly higher risk for complications after surgery than women undergoing 2G procedures (p<0.0001), whereas those undergoing 1G procedures or curettage were at significantly lower risk than patients treated by 2G procedure (p<0.0001).
