Results from sensitivity analyses examining the difference between CMR parameters in MHT users ≥ 3 years and propensity-matched controls are presented in Table 5. There were 429 matched participants in each group. As in multivariable regression models (Table 3), LV end-diastolic volume (MHT users = 117.5 ml vs never users = 121.7 ml, mean difference = -3.2%, 95% CI: -5.5% to -0.9%; p = 0.007), LV stroke volume (MHT users = 70.9 ml vs never users = 73.8 ml, mean difference = -3.7%, 95% CI: -6.1% to -1.3%; p = 0.003) and LA maximal volume (MHT users = 56.8 ml vs never users = 59.4 ml, mean difference = -4.9%, 95% CI: -8.9% to -0.8%; p = 0.019) were significantly lower in MHT users ≥3 years. S2 Table details the balance between the co-variates both before and after propensity-matching.
