We always suggest that researchers use syntax (as opposed to Remember that a constant factor change in the odds does not It was also found that, holding studying program constant, the odds of passing the final exam increased by .6% (95% CI [.002, .009]) for each additional hour studied. For reference, the model has a binary outcome, a continuous covariate and two categorical predictors.
