“…In a recent meta-analysis, Liu et al [9] found no significant association between LS7 as a continuous variable and AF in a pooled analysis of 3 cohort studies with a total of 3,700 incident cases of AF (HR 0.94 [95% CI: 0.86e1.01]; I 2 Z 97.7%), although the individual studies reported a small but significant decrease in the risk of AF. There was substantial heterogeneity between these studies and differences may be related to diverse reasons.…”
