Figure 2. Inverse Probability of Treatment–Weighted Survival Curves among Women with Stage IA2 or IB1 Cervical Cancer, According to Type of Surgery.

Figure 2.

Shaded bands represent the 95% confidence interval. Women who underwent minimally invasive surgery had shorter overall survival than those who underwent open surgery (P = 0.002 by the log-rank test). The at-risk table shows the actual number of patients at risk. The inset shows the same data on an enlarged y axis.
