This model has a log-transformed response variable, and exponentiated
parameters are reported.
A one-unit increase in the predictor is associated with multiplying the
outcome by that predictor's coefficient.

This model has a log-transformed response variable, and exponentiated
parameters are reported.
A one-unit increase in the predictor is associated with multiplying the
outcome by that predictor's coefficient.
