Quality of Life in Chronic Kidney Disease Patients and Hemodialysis Patients
Bibliographic record
Abstract
The aim of this cross‐sectional study is to assess quality of life (QOL) in 119 chronic kidney disease (CKD) patients and 89 hemodialysis (HD) patients using the SF‐36 instrument (PF = physical function, RP = role limitations physical, BP = bodily pain, GH = general health perceptions, VT = vitality, SF = social function, RE = role limitations emotional, MH = mental health, MCS = mental summary, and PCS = physical summary). The mean (range) s‐creatinine in the CKD group was 325 μmol/L (133–809 μmol/L). There were no differences in SF‐36 scores between CKD and HD patients (Figure). CKD/HD status did not predict MCS or PCS in multivariate analyses controlling for age (p < 0.01 for PCS), sex, depression (p = 0.01 for PCS), Charlson comorbidity score (p < 0.01 for PCS), s‐albumin (p = 0.05 for PCS), hemoglobin, presence of partner, and level of education. We conclude that QOL is related to comorbid illness and decreases even before dialysis is started. Longitudinal studies of QOL in CKD patients are needed to evaluate the influence of dialysis initiation on QOL.

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.
