The low R2 value reflects the lack of ability of the model to predict whether a breath acetone value will be higher or lower than the sample mean. The model accounts for 8% of the variation in breath acetone. |

The explanatory variables have low Chi-Square (LR) statistic values and high p-values indicating each variable contributes little to the predicting model. |
