It seems there may have been at least 212 shows and 1062 listed appearances. With 5 people per show, iPlayer and Comedy.co.uk have 0% more appearances listed than required (and probably a similar percent of people) perhaps due to listing special guests. The host/captains/regulars have included Alan Davies (Regular × 212), Stephen Fry (Host × 187), Sandi Toksvig (Host × 25, Panellist × 17).

This Independent article from 2009 talks about the lack of women on QI.
I'd previously used IMDB as a source for QI but it over-estimated appearances by 25%. I first switched to comedy.co.uk and later to iPlayer as a source. IMDB seems to have been over-estimating the number of women more than it over-estimated the men!
In 2016 Sandi Toksvig took over from Stephen Fry as host of QI. Having a woman as a regular is one way to make a large difference to the overall stats.
