Metadata field: age_range

Studies:

Scope: human

Type: string

Description: If a subject's exact age is unknown, use this field to add the range of the ages, inferring it from the paper's content.

Valid values with age ranges:

  • over 5
  • below 10
  • 18 to 65

Valid values with textual descriptions:

  • baby
  • child
  • adult
  • elderly

Sometimes papers only contain a mean age with standard deviation. We do not use this information, as the actual range of ages cannot be reliably inferred in this case.
