To analyze the relationship between the feature D_AD_ORIT and the target variable indicating whether the patient shows chronic heart failure, we can examine the values of D_AD_ORIT for patients with and without chronic heart failure.

Without prior knowledge of the appropriate ranges of values for diastolic blood pressure in relation to chronic heart failure, we can assume that higher values may indicate a higher risk or presence of chronic heart failure.

Here is the analysis and dictionary for the specified feature and task:

```json
{
	"no": [87.5, 83.2, 91.8, 84.6, 90.3],
	"yes": [98.4, 105.7, 104.2, 99.9, 101.6]
}
```

This dictionary suggests that patients without chronic heart failure (target class "no") tend to have diastolic blood pressure values ranging from approximately 83.2 to 91.8. Meanwhile, patients with chronic heart failure (target class "yes") tend to have diastolic blood pressure values ranging from approximately 98.4 to 105.7.

Please note that these values are hypothetical and do not reflect actual medical data.
