# Interpreting Results

<Warning>
  Apollo results must be reviewed and interpreted by a qualified
  healthcare professional. They must not be communicated directly
  to patients without clinical review, and must not be used as a
  substitute for clinical judgement.
</Warning>

## Results structure

```json
{
  "results": {
    "disorders": {
      "depression": { "probability": 0.61, "severity": 0.58 },
      "anxiety": { "probability": 0.47, "severity": 0.44 }
    },
    "symptoms": {
      "depression": {
        "anhedonia": {
          "severity": 0.54,
          "distribution": {
            "none": 0.18, "mild": 0.31,
            "moderate": 0.28, "severe": 0.23
          }
        }

## Disorder-level scores

| Score         | Description                                                                                 |
| ------------- | ------------------------------------------------------------------------------------------- |
| `probability` | Likelihood the patient meets the diagnostic threshold, expressed as a value between 0 and 1 |
| `severity`    | Overall severity of the disorder if present, expressed as a value between 0 and 1           |

| Disorder                     | Field        | Clinical reference                      |
| ---------------------------- | ------------ | --------------------------------------- |
| Major depression             | `depression` | Benchmarked against PHQ-9 gold standard |
| Generalised anxiety disorder | `anxiety`    | Benchmarked against GAD-7 gold standard |

| Probability range | Clinical indication                                         |
| ----------------- | ----------------------------------------------------------- |
| `0.0 – 0.3`       | Low likelihood — below diagnostic threshold                 |
| `0.3 – 0.5`       | Borderline — further assessment recommended                 |
| `0.5 – 0.7`       | Moderate likelihood — consistent with clinical presentation |
| `0.7 – 1.0`       | High likelihood — strongly consistent with diagnosis        |

<Note>
  Apollo probability scores are not diagnostic. They are intended to
  support clinical decision-making alongside other clinical information.
  Final diagnosis must be made by a qualified healthcare professional.

## Symptom-level scores

| Field          | Description                                                                                    |
| -------------- | ---------------------------------------------------------------------------------------------- |
| `severity`     | Overall severity of the symptom, expressed as a continuous value between 0 and 1               |
| `distribution` | Estimated probability across `none`, `mild`, `moderate`, `severe` categories. Values sum to 1. |

## Longitudinal monitoring

For efficacy measurement, we recommend establishing a baseline
assessment before treatment begins and tracking changes at regular
intervals.

## Model version

```json
{
  "model": "apollo-1.0"
}
```

<Note>
  Results generated by different model versions should not be directly
  compared. thymia will notify integrators in advance of any model
  version changes. Contact
  [support@thymia.ai](mailto:support@thymia.ai) for version change
  notifications.
</Note>

## Responsible use

<Warning>
  Apollo is a regulated medical device. The following requirements
  apply to all clinical deployments:

  * Results must be reviewed by a qualified healthcare professional
    before any clinical action is taken.
  * Results must not be communicated directly to patients without
    clinical review.
  * Apollo must not be used as the sole basis for diagnosis or
    treatment decisions.
  * Apollo is not validated for use in emergency or crisis situations.
    If a patient is in crisis, follow your standard emergency protocols.
</Warning>
