Here is a list of each metadata field, with explanations where relevant
| Attribute | Description |
|---|---|
| patientid | Internal identifier |
| offset | Number of days since the start of symptoms or hospitalization for each image. If a report indicates "after a few days", then 5 days is assumed. This is very important to have when there are multiple images for the same patient to track progression. |

| extubated | Yes (Y) if the patient was successfully extubated or No (N) or blank if unknown |
| temperature | Temperature of the patient in Celsius at the time of the image |
| pO2 saturation | partial pressure of oxygen saturation in % at the time of the image |
| wbc count | white blood cell count in units of 10^3/uL at the time of the image |
| neutrophil count | neutrophil cell count in units of 10^3/uL at the time of the image |
| lymphocyte count | lymphocyte cell count in units of 10^3/uL at the time of the image |
| view | Posteroanterior (PA), Anteroposterior (AP), AP Supine (APS), or Lateral (L) for X-rays; Axial or Coronal for CT scans. Translations: Bettaufnahme->Supine, Liegend->Supine |
| modality | CT, X-ray, or something else |
| date | Date on which the image was acquired |
| location | Hospital name, city, state, country |
| filename | Name with extension |
| doi | Digital object identifier (DOI) of the research article |
| url | URL of the paper or website where the image came from |
