Sensitivity of combined circulatory disease risk estimates to study exclusion (excess relative risk (ERR)/Sv plus 95% CI) [all assuming as baseline inclusion of Muirhead et al. (2009) and exclusion of McGeoghegan et al. (2008) (as per bottom row of Table 2)] and contribution to heterogeneity χ2 statistic (+degrees of freedom, df)
