Abstract

fetched live from OpenAlex

Reply: We thank Drs Venditolli, Lavigne, and Roy for their comments regarding our article.1 They have correctly pointed out the unit error we unfortunately failed to note in the editing process. The units should have been nmol/L. We agree it is difficult to compare much of the literature on serum ion levels because of the vast methods of collection, analysis, and units used. It may be prudent for those involved in this type of research to agree to a set unit of measurement for published material, therefore stopping the reader from having to make complex calculations to ensure correct comparisons. We also agree including the standard deviations from the mean would be useful and probably should have been included. However, we are uncertain high levels indicate increased risk of metal ion-related complications and are unaware of any evidence supporting this view. Some of our patients did start with higher than expected preoperative levels and these patients subsequently had some of the highest postoperative levels, but we have no evidence at 4 years that this is a cause for concern. However, with a small sample size, we must be careful not to extrapolate the data too far. A much larger prospective study incorporating, different head sizes, weights, gender, and metallurgy is required before we can safely answer questions like this. D. L.

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.
