The data this analysis has yielded should be interpreted with caution.

Despite the widespread notion that more frequent citations mean better quality, this assumption holds only in certain cases, and the lack of impact does not mean that ompact journal lacks quality or does not fulfill a useful role in knowledge transmission.
