Abstract
Commentary on : Poordad F, Hezode C, Trinh R, et al. ABT-450/r-ombitasvir and dasabuvir with ribavirin for hepatitis C with cirrhosis. N Engl J Med 2014;370:1973–82.[OpenUrl][1][CrossRef][2][PubMed][3][Web of Science][4] The prevalence of hepatitis C virus (HCV) reached its peak in 1994 and is expected to decrease significantly over the next few years. However, HCV-related cirrhosis continues to increase. Razavi et al 1 predicted that decompensated cirrhosis will reach its peak in 2019. This translates into increased healthcare costs secondary to complications of cirrhosis. Patients with cirrhosis due to HCV infection are less likely to achieve a sustained virological response (SVR), even in the era of direct-acting antivirals (DAA). Only 62% of genotype-3 cirrhotics treated with sofosbuvir and ribavirin for 24 weeks achieved SVR compared with 87% of non-cirrhotics.2 Treatment of advanced cirrhosis brings increased risks of … [1]: {openurl}?query=rft.jtitle%253DN%2BEngl%2BJ%2BMed%26rft.volume%253D370%26rft.spage%253D1973%26rft_id%253Dinfo%253Adoi%252F10.1056%252FNEJMoa1402869%26rft_id%253Dinfo%253Apmid%252F24725237%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [2]: /lookup/external-ref?access_num=10.1056/NEJMoa1402869&link_type=DOI [3]: /lookup/external-ref?access_num=24725237&link_type=MED&atom=%2Febmed%2F20%2F1%2F6.atom [4]: /lookup/external-ref?access_num=000336125500005&link_type=ISI

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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, unvalidatedLabeled directly by 2 models reading the full record.
