The perils of correlation:

"There was also a significant positive effect of N. ceranae on colony growth in the May-September period of the first year (an increase of 0.07 frames per 1 million N. ceranae per bee;Pof 0.04). This effect was relatively small to observe negative effects and was probably biologically inconsequential."

Inconsequential, but statistically entertaining. You don't often get this level of "inside baseball" in a paper, these sorts of artifacts are dropped from publication more often than not.
