Question: is this a 2) strong advice, 1) weak advice 0) no advice?

Despite the number of SSc patients in our study was much higher than in original report [13], in one particular situation it may be considered as “suboptimal:” our study may not be powerful enough to detect possible “true association” in case that it would be much weaker than observed in initial German study [13].
