You’ve been dupe’d: Nice data — let’s see them again

As we’ve said before, with hundreds of retractions per year, there are simply too many for us to cover individually. So from time to time we’ll compile a list of retractions that appeared relatively straightforward, just for record-keeping purposes. Often, these seemingly straightforward retractions involve duplications, in which authors — accidentally or on purpose — […]

The journal is not retracting the paper outright, it says, because the study was non-invasive and likely would have received ethics approval. During the study, teenagers with and without progressive scoliosis underwent […]
