Survival comparison between narsoplimab-treated patients with TA-TMA and the KSCTG TA-TMA group. Forest plot of estimated HR and 95% CIs for the 3 primary comparative survival analyses and corresponding sensitivity analyses. The vertical line represents value at which risk of mortality between the comparator groups would not be different. Values to the left of the line would indicate reduced risk of mortality with narsoplimab treatment and values to the right would indicate increased risk of mortality with narsoplimab treatment. RF, risk factor.
