Fig. 4: Overall survival in the inverse probability of treatment weight–adjusted analysis in AAD patients suffering from ARR (blue) or VSRR (red).

This figure depicts the survival probability over time for two groups, distinguished by color coding. The horizontal axis represents the time in months since diagnosis until death or last contact, while the vertical axis indicates the survival probability. Blue represents the “No” group (ARR), and red represents the “Yes” group (VSRR). The chart also displays the number of patients at risk at various time points. Upon application of the inverse probability of treatment weighting (IPTW) analysis, a statistically significant advantage in survival emerged for the VSRR group compared to the ARR group, with a p value of < 0.001 (p< 0.001), indicating a clear distinction between the two groups.
