Corrigendum: Urinary Luteinizing Hormone Tests: Which Concentration Threshold Best Predicts Ovulation?
Bibliographic record
Abstract
Error in Figure/TableIn the original article, there was a mistake in ** Table 3. The Sensitivity (Se), Specificity (Sp), Positive Predictive value (PPV), Confidence Intervals (CI), Negative Predictive value (NNV) ,Likehood Ratios +’ve (LR+) and Likehood Ratios -’ve (LR-) for predicting ovulation within 24 hours at 15, 20, 25, 30, 35 and 40 mIU/ml thresholds on the 11th day of the cycle** as published. **Upon review of the tables prior to a journal club, it was noted that there were some numerical values that had been inadvertently misplaced under the wrong columns when updating different previously edited tables **. The corrected **Table 3** appears below. The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.

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.
