Fig. 1: Changes in echocardiographic parameters from baseline to month 30 in the vutrisiran versus placebo groups in the overall and monotherapy populations.

a–h, LS mean changes in mean LV wall thickness (a), LV mass index (b), lateral e’ velocity (c), lateral E/e’ (d), LVEF (e), absolute GLS (f), LV stroke volume (g) and RV S’ (h) from baseline to month 30 for vutrisiran versus placebo for the overall and monotherapy populations. Dots represent the LS mean change from baseline to month 30 and the error bars represent the s.e.m. Sample size for each echocardiographic parameter can be found in Table 2.
