It might be noise, but you can't tell from N=42 alone. It is possible to find "significant" results with small groups (my back-of-the-envelope calculation suggests that the proportion of success between the groups must differ by more than 30 percentage points to be p<0.05). They might well have done the maths and might have highly significant p-values. Note the supplementary materials [1]. I don't understand them without the paper, but they sure do have a lot of "*** p < 0.001" results. (Entirely unrelated side note: A shame that Sci-Hub currently does not add papers due to litigation...)
