Étude de la variabilité cardiaque chez les Inuit adultes du Nunavik exposés au mercure
Bibliographic record
Abstract
Le présent projet vise à déterminer l'impact du mercure sanguin sur la variabilité cardiaque (VC) chez des adultes du Nunavik en tenant compte des concentrations des oméga-3 et d'autres facteurs potentiellement confondants. Des échantillons sanguins ont été prélevés chez 280 adultes de 40 ans et plus et, des électrocardiogrammes ambulatoire de type Holter ont été enregistrés pendant 2 heures consécutives afin de calculer des indices de temps et de fréquence de la VC. En corrélation simple, le mercure n'a été associé faiblement qu'à la basse fréquence (LF) (r= -0.18; p= 0.02) et à la déviation standard des intervalles RR (SDNN) (r= -0.14; p= 0.047) mais ces associations sont devenues non significatives après le contrôle statistique des facteurs confondants (|3= -0.09, p= 0.35; p= -0.04, p= 0.37 respectivement). En conclusion, aucun effet du mercure sur la VC n'a pas été constaté dans cette population.

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.
