English: This chart shows how reading times predicted by a regression model change as the development level of the country changes. This model (model 3v2) includes an interaction between mobile and whether the view is the last in a session in an attempt to account differences in behavior. This term improved the fit and predictive performance of the model, but it also lead to a change in conclusions. Including the term reveals that, once we statistically account for the last-in-session variable, that the "device gap" appears to vanish, at least in developed countries. As non-mobile readers actually dwell on pages for less time than mobile readers.
