"Among other things, these applications have revealed that the misuse of ordinal scaled data can produce erroneous data and drive inaccurate conclusions. Consequently, concerns must be raised over the accuracy of the results of the meta-regression performed by Kirsch et al, given they have undertaken sophisticated mathematical operations on data which do not support such activities. Moreover, it is worth noting that even the calculation of a mean, a standard deviation, and a change score are invalid on ordinal data, given that these all assume equal interval scaling."
no no no! tell me it ain't so-- the authors conducted parametric statistical tests on ordinal statistics? (can you hear me retching?)Once upon a time I was a "peer" and reviewed some truly outrageous papers, a couple of iffy ones, and one good one. There was also the paper that my advisor said "must come from lab X... very esteemed lab...I'm sure it's great..." leaving the peon llurpsie little option but to overlook significant editorial issues and infer meaning and conclusions where none were written. barf.
Maybe I have the energy to read this entire thread, now that I've interrupted it.
