<![CDATA[Canine acute-pain assessment combines behavioral observation, clinical context, and professional judgment, yet a model probability can be mistaken for a clinical pain score when the two lack a clear visual hierarchy. This study linked retrospective prediction-model findings to three information-equivalent interface prototypes. The structured database contained 594 observations from 184 dogs; 114 complete acute-pain observations from 65 dogs formed the primary cohort, with the short-form Glasgow Composite Measure Pain Scale (CMPS-SF) ≥ 6/24 as the reference outcome. A hypothetical pre-score feature set excluded direct score components, although the database did not establish recording order. Four calibrated models were evaluated with five repetitions of four-fold dog-grouped nested cross-validation. Logistic regression achieved an area under the receiver operating characteristic curve (AUROC) of .627 (95% CI [.474, .755]), an area under the precision–recall curve (AUPRC) of .476 [.317, .660], and Brier score .210 [.174, .249]. Sensitivity at 0.50 was .189, missing 30 of 37 threshold-positive observations. Full-development bootstrap fits supplied 90% model-stability ranges, distinct from patient-outcome intervals. Exploratory routing reduced Brier score but also reduced AUROC and changed retained event prevalence. An auxiliary vocabulary analysis identified 169 descriptors in 52 grouped rows. A separate transit-display analysis of 12,331 records from 299 participant identifiers did not establish an average payoff or duration advantage over a no-uncertainty display. The numeric dashboard, visual scale, and progressive evidence card retained identical information while varying hierarchy and disclosure. Their structural audit establishes content equivalence, not clinical effectiveness. The design contribution connects model limitations to visible range definitions, separate clinical-reference labels, missing-context cues, and a persistent structured-assessment action.]]>
