Question 1: The authors say that the main outcome measures for this study are ‘odds ratios for risk of glioma in relation to mobile phone use’. Is this correct?
The outcome measure in a research study is not the results of the analysis but the variable which we are trying to predict. We could take two views of this in a case control study: it is either the possible causal variable, mobile phone use, or the possible consequence of this variable, glioma.
