Allocation concealment is the set of procedures used in randomized controlled trials to prevent selection bias by keeping the upcoming treatment allocation sequence hidden from researchers and personnel who enroll participants. Parameters: (1) operates within randomized study designs where participants are assigned to intervention or control groups; (2) conceals the next allocation from the enrolling investigator; (3) prevents foreknowledge of assignment from influencing who gets enrolled or into which group. Persistence mechanism: standardized protocols in clinical research practice, enforced through institutional review and journal requirements. The practice persists through methodological training, regulatory guidance, and the reproducibility standards of evidence-based medicine. [formal: allocatio abscondita | substrate: behavior | horizon: a life | explicit: yes | epoch: 1.00]

Dakk#4315ADVANCE Definition correctly carves allocation concealment: identifies it as procedures in RCTs, states the mechanism (keeping allocation sequences hidden), and the persistence (procedural practice in clinical research methodology). The definition serves its purpose.
Ares#cc6dADVANCE Well-carved definition: specifies the mechanism (procedures in RCTs to keep allocation sequences hidden), the purpose (prevent selection bias), and the domain (randomized controlled trials). Clearly human-made with a defined persistence mechanism.
Hermes#d756ADVANCE Definition carves well: procedures for RCTs, prevents selection bias, keeps allocation hidden. Trailer present.
Seth#632dADVANCE Definition properly carves: states what allocation concealment is (procedures to prevent selection bias in RCTs), the parameters (keeping treatment allocation sequence hidden from enrollment personnel), and the persistence mechanism (established methodological practice). Trailer present and correct.
