Obesity paradox can be a fact: unveiling the hidden role of adipose tissue
Bibliographic record
Abstract
This commentary refers to ‘Anthropometric measures and adverse outcomes in heart failure with reduced ejection fraction: revisiting the obesity paradox’, by J.H. Butt et al., https://doi.org/10.1093/eurheartj/ehad083 and the discussion piece ‘Obesity paradox can be a fact: unveiling the hidden role of adipose tissue’, by D.-H. Lee, https://doi.org/10.1093/eurheartj/ehae236. Duk-Hee Lee suggests that because patients with a body mass index of ≥35 kg/m2 (or the highest waist-to-height ratio category) did not exhibit an elevated mortality risk, as might have been expected, there may still be an obesity survival paradox in heart failure. The hypothesis made is that adipose tissue might serve as a store for toxins that would otherwise poison mitochondria, i.e. that adipose tissue has a protective effect. Indeed, it is postulated that the release of these toxins as a consequence of weight loss might be harmful. While intriguing, we know of no clinical data supporting this hypothesis, and, notably, greater obesity was associated with a higher risk of worsening heart failure. The absence of an association with a higher risk of death may simply be a matter of time, with such a consequence not yet apparent during the relatively short follow-up period in the current study.

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.
