Downloaded the PMC HTML of Davis, Brakora and Lee 2011 and parsed the only table. Section headers are colspan rows. The regeneration block has three scored rows. A cell counts as present only for '+' or '+/−'; parentheses and '?' do not. Cervids are present for regeneration of bone and of integument. Antilocaprids are present for regeneration of the keratin sheath. Bovids and giraffids are absent on all three rows. The caption and cells do not state an annual period or an onset after two years of age.

Measured: 1 non-cervid headgear groups marked present for a regeneration character (n = 4). Interpretation: Deer is the family Cervidae. 'Sheds its horns and grows them again' is regeneration of the headgear, whether the cast tissue is bone or the keratin sheath, because the sentence says the horn is shed and renewed and does not restrict the tissue. Age at first cast and an annual period are read only from words in the same table; they are not supplied from elsewhere. The denominator is the headgear groups that are columns of the table, not a species count.

A checksummed published character table that scores shedding or regeneration of cranial appendages for the extant horned groups, with the groups named so that deer can be separated from other horned animals. A narrative mention without a table of groups is not admissible. AnAge, PanTHERIA and FishBase do not record this character.

A plus is a family-level state. It does not say that every species in the family sheds, or that every deer starts after two years of age.

Deviation from the pre-registered row match: the word regeneration is a section header, and the scored labels underneath it do not repeat that word. Those three subrows were scored. See deviations.

The annual cycle and the age of two years are not in the table. The refutation is the uniqueness clause: antilocaprids, which are not deer, are marked present for regeneration of the keratin sheath.

The denominator is the four extant ruminant headgear groups in Table 1, not a species count. Rhinoceroses and other horned animals outside that table are untested.

Cervids are the only column marked present on a regeneration row, and the table states an annual cast beginning after two years of age.
https://w3id.org/delphi/resource/assessment/aristotle-ha02-04--claim-test
https://w3id.org/delphi/ontology/failCriterion
Pre-registered. Refute if any non-cervid column is marked present for a regeneration character, or if cervids are not marked present for any regeneration character. If cervids are the unique regenerating column but the table does not state an annual cycle and an onset after two years of age, the verdict is mixed: uniqueness of shedding-and-renewal holds and the schedule is untested. Inconclusive with reason data-unavailable if that table cannot be fetched or cannot be parsed into those columns. Inconclusive with reason not-operationalizable if no regeneration row can be identified.

https://w3id.org/delphi/ontology/hypothesis
If the claim holds, then among extant ruminant groups that bear headgear, only the deer (cervids) cast and renew that headgear, the cast is annual, and it begins after two years of age.
https://w3id.org/delphi/resource/assessment/aristotle-ha02-04--claim-test
https://w3id.org/delphi/ontology/inferenceMethod
Parse the published table. Score each column on regeneration rows. Uniqueness fails if any non-deer column is '+' or '+/−' on any such row. The schedule clauses pass only if the table text itself contains the annual period and the age of two years. Report the number of columns as the denominator.
https://w3id.org/delphi/resource/assessment/aristotle-ha02-04--claim-test
https://w3id.org/delphi/ontology/passCriterion
Pre-registered. In Davis, Brakora and Lee 2011, Table 1 (family-level headgear characters for cervids, bovids, giraffids and antilocaprids), cervids are marked present for at least one regeneration character and no other column is marked present for any regeneration character, and the table caption or cells state both that the shedding is annual and that it begins after two years of age. A '+' or a '+/−' is present. A parenthetical '(+)' or a '?' is not present. Regeneration characters are rows whose label contains 'regeneration'.
