Meta-analysis has been defined as “the process of aggregating the data and results of a set of studies, preferably as many as possible that have used the same or similar methods and procedures; reanalyzing the data from all these combined studies; and thereby generating larger numbers and more stable rates and proportions for statistical analysis and significance testing than can be achieved by any single study”. But this is almost never the case for meta-analyses of ETS, performed from cherry-picked and dissimilar studies to demonstrate a politically pre-conceived outcome: that the prohibition of smoking is legitimate because passive smoking hurts people. But the meta-analysis of studies that prove nothing cannot prove anything.
