"Figure 4.39: Survival functions plotted using the Cox proportional hazard model, for logged authors in the top ten Wikipedias. Control variables where: 1) authors who did not revised either FAs or talk pages (black); 2) authors who revised talk pages but did not contributed to FAs (red); 3) authors who performed revisions in FAs but not in talkpages (green); 4) authors who revised both FAs and talk pages (navyblue). The graph shows that the survivability of logged authors who revised FAs and participated in talk pages is substantially higher than that of authors who did not participated in FAs or discussion processes."
