Table 5.
Variables that best explained the variability in use of traditional medicines in the last 12 months. Information on the most parsimonious model obtained when using AIC or BIC during model selection is presented. Negative values for the deviance to the reference level imply a lower probability of TM use than the reference group (deviance = 0).
