I am trying to look at the association between a polymorphism and risk of cancer incidence by a meta-analysis. However for some studies we do not have the complete genotype information for the same. We noted allele distribution from the publications and tried to contact authors to obtain the complete genotype data. Some of them, however, haven't responded. So we have done a primary analysis including only studies that have the complete genotype data. Now I wish to do a sensitivity analysis by including the omitted studies and perform the comparisons with the available data. Is this approach correct? or unnecessary?
