Findings from the meta-analysis on total water intake and CVD
mortality:
Five cohort studies examined the association between total water intake
and risk of CVD mortality[5, 6, 14-16]. These
studies included a total of 91051 participants among them 7107 mortality
cases were found. The summary effect size for CVD mortality, comparing
the highest and lowest total water intakes, was 0.84(95% CI: 0.77-0.93,
P<0.001), indicating a significant inverse association between
total water intake and risk of CVD mortality (Figure 4 ). No
significant heterogeneity among the studies was observed
(I2 = 0%; P = 0.76).
