the question and the data tabulation is below (so that's the basis for the categorisation of our study participants for pedestrians and cyclists). I am unsure what is non-active (all others????)

Interesting. From this info, I would assume that the typical BF "enthusiast" who rides a bicycle for recreational, competition, fitness, trail riding, group rides, etc., but not commuting purposes fits into the non-active (other) category.
The unanswered question arises then what is so special about bike commuting and by what mechanism it allegedly reduces the risks of diseases such as cancer and does it apply to all other types of "active" bicycling?
