^aOR [99% CI] denotes the odds of scoring satisfaction one level higher per one unit increase in the covariate, with all other factors held equal.

^bOverall model was significant (P < 0.001) with a pseudo-R² of 0.01.

^cUsage counts are scaled and transformed by a normalizing factor.

^dCollinear factors omitted from the model.
