- * Change is relative to the pre-HAART value for an individual, thus a positive value for change in MCH indicates an increase in MCH for an individual from their pre-HAART value.
- ** The intercept has no OR interpretation.
- *** To determine the predicted probability of having an HIV RNA > 500 copies/ml for an individual, take the value of each variable and multiply it by the corresponding Beta Coefficient. Take the sum of the resulting values and add the Intercept Beta Coefficient. This is the log(odds) that an individual has an HIV RNA value above 500 copies/ml. The predicted probability is then 1/(1+e(-log(odds)).
