The Role of Older Age in Normocytic Anaemia in Type 2 Diabetes Mellitus
Bibliographic record
Abstract
BACKGROUND: Older age has a significant association with anaemia. However, this has not been adequately investigated in the context of specific comorbidities such as Type 2 Diabetes Mellitus (T2DM). OBJECTIVES: To investigate the role of age in Normocytic Anaemia (NCA) and the adverse outcomes of NCA in T2DM. METHODS: Patients with NCA, either unexplained or related to Chronic Kidney Disease (CKD), were recruited from a diabetic clinic over six months. Anaemia was defined as a haemoglobin(Hb) < 130g/l for men and <120g/l for women. The relevant data were obtained by interviewing patients and review of medical records. Patients were followed for 12 months for pre-defined adverse outcomes. RESULTS: Of the 354 patients assessed, 203 were included (mean age 63.12 ± 13.62 years, males 49.8%). The prevalence of NCA was 24% (49). Older age had a significant univariate association with NCA (p < 0.001) and this remained significant (adjusted Odds Ratio (OR) 1.24, 95% CI 1.16- 5.29) after adjusting for estimated Glomerular Filtration Rate (eGFR) < 60ml/min/1.73m2, albuminuria and other potential confounders. Adjusting for eGFR as a continuous variable also confirmed this significant association (OR1.15, 95% CI 1.10-7.01). In the subgroup of patients aged ≥ 75 years, only older age was significantly associated with NCA. The incidence of all-cause mortality and composite cardiovascular/cerebrovascular events was similar in the anaemic and nonanaemic groups. CONCLUSION: NCA is common in T2DM and has a significant association with older age independent of CKD. The anaemia is mild in most patients and appears to have a benign course.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
