Only patients who logged into MyChart were included in these models. Note that these are odds ratio for the odds of not performing an activity given an individual had logged in. These odds were modeled as part of individual zero-inflated maximum-likelihood Poisson models to estimate both (1) the odds of not performing an activity and (2) the number of each of the 3 activities. Bold values are significant at P < .05.
FPL, federal poverty level.
