*Note that this summary measure can only be calculated if, in addition to the subgroup estimates, information about the number of people affected or at risk within each subgroup have been entered in the uploaded database (variable ‘population’ in the HEAT Plus template).
**Note that this summary measure can only be calculated if, in addition to the subgroup estimates, standard errors of subgroup estimates and information about the number of people affected or at risk within each subgroup have been entered in the uploaded database (variables ‘se’ and ‘population’ in the HEAT Plus template).
