Measurement properties of an assay measuring suprathreshold intensity and acceptability for chicken broth containing different amounts of sodium chloride
Bibliographic record
Abstract
It was assessed the reliability of an assay aimed at measuring the suprathreshold intensity and acceptability for chicken broth containing different amounts of sodium chloride, according to the criteria of temporal stability, among adults. Both intensity and acceptability were measured using a 9-point scale (“not salty at all” to “extremely salty” for intensity and “dislike it extremely” to “like it extremely” for acceptability). Results indicated that the intensity ratings increased gradually throughout the nine concentrations ranging from 1.7 to 7.9. The highest level of acceptability corresponds to the concentration of 255 mg of Na/100ml with a rating score of 6.3. The intensity and acceptability values varied greatly among concentration and participants. The temporal stability was assessed over a period of 7 to 15 days. There was no statistically significant difference between the two sessions for the suprathreshold and acceptability scores, regardless of the concentration. The Intraclass Correlation Coefficient (ICC) was significant for one concentration in the intensity scores (ICC = 0.54) and for 4 out of 6 concentrations of the acceptability scores, varying from 0.35 to 0.64. The test covers a range of concentrations consistent with sodium levels found in commercially available products. Due to the limited number of subjects in this study, further work is needed to better describe its measurement properties.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
