Abstract

fetched live from OpenAlex

Quality of life (QOL) optimization is an important issue during the process of care for patients suffering from a life-threatening illness such as cancer. The Quality of Life in Life-Threatening Illness-Patient questionnaire (QOLLTI-P) is a self-administered questionnaire based on the McGill Quality of Life questionnaire (MQOL) with domains added to enhance content validity. This study's main objective was to assess the construct validity of QOLLTI-P in cancer patients. Cancer outpatients were asked to complete a set of questionnaires including QOLLTI-P and the Functional Assessment of Chronic Illness Therapy- Spiritual well-being scale (FACIT-Sp). An 8-factor structure was suggested for QOLLTI-P. In general, QOLLTI-P Total and subscale scores are highly correlated with their corresponding FACIT-Sp scores. In conclusion, QOLLTI-P is a valid instrument to assess the QOL of cancer patients.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
